Question

Is hydrogen bond weaker than covalent bond?

Answer 1

Covalent Bond:

• The bond formed as a result of sharing of electrons between the atoms of the same element of the different elements.
• example: ${\mathrm{H}}_2,{\mathrm{H}}_2\mathrm{O}$ etc.
• The covalent bond is stronger because the electrons are paired while bonding which takes more energy to break the bond.

Hydrogen Bond is weaker than covalent bond:

• A hydrogen bond is formed when Hydrogen is attached to high electronegative elements like Flourine$\left(\mathrm{F}\right)$, Oxygen$\left(\mathrm{O}\right)$, and Nitrogen$\left(\mathrm{N}\right)$ interact with the electronegative elements of other molecules.
• It is a temporary bond as it is formed for a short interval of time.
• It is a special dipole-dipole interaction between molecules not a covalent bond with $\mathrm{H}$ atom.
• 
• The strength of the Hydrogen bond is about one-tenth of the Covalent bond.

So, The Hydrogen bond is weaker than the covalent bond.
