Question

How do covalent bonds differ from hydrogen bonds?

Answer 1

The covalent bonds are the chemical bond which are the result of equal sharing of electrons between the atoms. The hydrogen bonds are the electrostatic attraction between the hydrogen atom and the electronegative atom.

Complete step by step answer:
The chemical bonds are the stable attraction formed between the atoms or ions which keeps the molecule intact and forms chemical compounds.
The covalent bonds are the type of chemical bonds formed by the sharing of electrons between the two atoms
The hydrogen bonds are the weak electrostatic attraction between the hydrogen and an electronegative atom which is formed because of the electronegativity difference.
The difference between covalent bonds and hydrogen bonds is given below.
Covalent bond:
(1) The covalent bonds are usually strong bonds.
(2) The bond energy of covalent bonds is between 100 to 1100 KJ/mol.
(3) The covalent bonds are primary bond
(4) The covalent bonds change the chemical properties of the atom taking part in bonding.
(5) The covalent bonds always form an intramolecular bond.
(6) The covalent bond is formed between the polar and nonpolar atoms.
Hydrogen bond:
(1) The hydrogen bonds are usually weak bonds.
(2) The bond energy of hydrogen bonds is between 5 to 50 KJ/mol.
(3) The hydrogen bonds are secondary bonds.
(4) The hydrogen bond changes the physical properties of the atom taking part in bonding.
(5) The hydrogen bond always forms an intermolecular bond.
(6) The hydrogen bond is formed between polar atoms.

Note:
Individual hydrogen bonds are considerably weak bonds but their presence in large amounts helps to gain considerable strength.
