What makes bonds stronger or weaker?
The strength of a bond between two atoms increases as the number of electron pairs in the bond increases. Thus, we find that triple bonds are stronger and shorter than double bonds between the same two atoms; likewise, double bonds are stronger and shorter than single bonds between the same two atoms.
One molecule's positive end will attract the negative end of another molecule nearby. Therefore, the order from strongest to weakest bond is Ionic bond > Covalent bond > Hydrogen bond > Vander Waals interaction.
In chemistry, covalent bond is the strongest bond. In such bonding, each of two atoms shares electrons that binds them together. For example, water molecules are bonded together where both hydrogen atoms and oxygen atoms share electrons to form a covalent bond. Was this answer helpful?
Weak bonds are those forces of attraction that, in biological situations, do not take a large amount of energy to break. For example, hydrogen bonds are broken by energies in the order of 4–5 kcal/mol and van der Waals interactions have energies around 1 kcal/mol.
Bone is a living, growing tissue. It is made mostly of two materials: collagen (KOL-uh-juhn), a protein that provides a soft framework, and calcium (KAL-see-uhm), a mineral that adds strength and hardness. This combination makes bone strong and flexible enough to hold up under stress.
Chemical bonds may be divided into two groups: 1) covalent (strong) bonds in which atoms share electrons, and; 2) a variety of weak bonds, including electrostatic attractions (ionic bonds, hydrogen bonds), hydrophobic interactions, and Van der Waals forces.
Bond strength mostly depends on the charges present on each ion and the distance between them. Small, highly charged ions will form stronger bonds while large,minimally charged ions will form weaker bonds.
The ranking from strongest to weakest bonds is: Covalent bond > ionic bond > hydrogen bond > Van der Waals forces.
- Chemical bonds are formed by the interaction of molecules either in an attractive manner or in a repulsion manner.
- The weakest type of bonds are the Hydrogen bonds.
- Hydrogen bonds are formed when a Hydrogen atom is bonded to more electronegative atom.
Ionic bond: Ionic bonds are the strongest bonds because these are formed due to the electrostatic attraction of an electron from one atom to another. Covalent bond: These are also considered the strongest bond but not as much as an ionic bond, and these bonds are formed when the atoms share the pairs of electrons.

Multiple bonds are stronger than single bonds between the same atoms. The enthalpy of a reaction can be estimated based on the energy input required to break bonds and the energy released when new bonds are formed.
Strong acids and bases ionize fully in an aqueous solution. Weak acids and bases also ionize, but only partially and the reaction is reversible. So how do we know if an acid or base is strong or weak? A simple way to determine strength is to add the acid or base to water—high reactivity means a stronger acid or base.
Generally, the strongest types of chemical bonds are the ionic and covalent bonds. Chemical bonds are said to be covalent bond if the bond formed is a result of sharing of electrons between nuclei.
When a bond is strong, there is a higher bond energy because it takes more energy to break a strong bond. This correlates with bond order and bond length. When the Bond order is higher, bond length is shorter, and the shorter the bond length means a greater the Bond Energy because of increased electric attraction.
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length. Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
Explanation: Ionic bonds are the strongest type of bonds, followed by covalent bonds, hydrogen bonds, and lastly, van Der waals forces.
There are three types of bonds that are important to biology: ionic (second strongest), covalent (strongest), and hydrogen (weakest).
Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.” Hydrogen Bonds: hydrogen attracts and bonds to neighboring negative charges.
What determines the strength of covalent bonds?
The strength of a covalent bond is measured by its bond dissociation energy, that is, the amount of energy required to break that particular bond in a mole of molecules. Multiple bonds are stronger than single bonds between the same atoms.
...
Bond Energy.
| Bond | Bond energy, kJ/mol |
|---|---|
| C–C | 347 |
| C=C | 615 |
| C≡C | 812 |
| C–O | 360 |
Energy can be stored in chemical bonds. The amount of energy in a bond is somewhat counterintuitive - the stronger or more stable the bond, the less potential energy there is between the bonded atoms. Let's repeat that on its own line: Strong bonds have low potential energy and weak bonds have high potential energy.
We know that the ionic bonds are more stronger than the covalent bond,so why it is slightly complicated to dissolve the covalent bonded compounds?
The strength of a covalent bond is measured by its bond dissociation energy, that is, the amount of energy required to break that particular bond in a mole of molecules. Multiple bonds are stronger than single bonds between the same atoms.
Hint: Covalent bonds are known to be the strongest and the bonds formed via Van der Waals forces are known to be the weakest. The ranking from strongest to weakest bonds is: Covalent bond > ionic bond > hydrogen bond > Van der Waals forces.

Chemical bonds have different strengths. Atoms that are more strongly attracted to each other have a stronger bond strength and are more stable. More energy is required to break stronger chemical bonds as compared to the energy required to break weaker chemical bonds.
The longer the bond the weaker the bond. The strongest bond is the Covalent Bond. There are a lot of ways in which atoms bond with each other.
Covalent bonds are the strongest (*see note below) and most common form of chemical bond in living organisms. The hydrogen and oxygen atoms that combine to form water molecules are bound together by strong covalent bonds. The electron from the hydrogen atom shares its time between the hydrogen atom and the oxygen atom.
- Chemical bonds are formed by the interaction of molecules either in an attractive manner or in a repulsion manner.
- The weakest type of bonds are the Hydrogen bonds.
- Hydrogen bonds are formed when a Hydrogen atom is bonded to more electronegative atom.
Are polar or nonpolar bonds stronger?
Thus, these opposite, partial charges attract each other. The more the atoms are charged, the higher the strength of their attraction. Thus, based on this, polar bonds can be said to be stronger than nonpolar bonds.
A covalent bond is formed when valence electrons are shared between two atoms, equally. They are also called molecular bonds. Sigma bond is considered to be the strongest bond, where head to head overlapping occurs between atomic orbitals.
Covalent bonds are the strongest bonds in nature and under normal biological conditions have to be broken with the help of enzymes. This is due to the even sharing of electrons between the bonded atoms and as with anything equally shared there is no conflict to weaken the arrangement.
