Question

What is the difference between a covalent bond and a hydrogen bond $?$

Answer 1

Hint : First we know chemical bonds are forces that hold atoms together to make compounds. Covalent bonds (polar and nonpolar bonds) form between two nonmetal atoms of similar electronegativities. Whereas hydrogen bonds are two types, intramolecular (chemical bonds) and intermolecular hydrogen bonds.

Complete Step By Step Answer:

Covalent Bond	Hydrogen Bond
Formed by sharing of pair of electrons between two atoms or molecules	Formed by dipole-dipole intermolecular attraction (weak electrostatic attraction) between hydrogen atoms and an electronegative atom
It is Strong chemical bond.	It is Weak chemical bond.
It is a Primary chemical bond.	It is a Secondary chemical bond.
It changes the chemical properties of bonding molecules.	It changes the physical properties of bonding molecules.
Examples of covalent bonds are ${H_2}O$(water), Carbon dioxide ($C{O_2}$), etc.	Examples of hydrogen bonds are ${H_2}O$(water) chloroform ($CHC{l_3}$), etc.

Note :
Note that primary bonds are formed when the bonding process involves a transfer or sharing of electrons. Secondary bonds are formed from the subtle attraction forces between positive and negative charges. Whereas the ionic bond is formed when an electron (or electrons) exchange between a nonmetal and a metal.
Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions are the four types of chemical bonds, which are essential for life to exist.
