Question

(a) What is a covalent bond? What type of bond exists in (i) CCl4, and (ii) CaCl2?
(b) What is an ionic bond? What type of bond is present in oxygen molecule?

Answer 1

Answer:

covalent bond is a bond between similar kind of atoms while ionic bond is between metal and non metals

1. CCl4 is an covalent bond

2. CaCl2 is a ionic bond

Answer 2

Transfer of Electrons makes Ionic Bonding

Explanation:

a.) The chemical bonds formed between two atoms by the sharing of electrons between them is known as a covalent bond.

• The sharing of electrons between the two atoms takes place in such a way that both the atoms acquire a stable electronic configuration of their nearest noble gas.

$CCl_4 - Covalent\ bond,CaCl_2 - Ionic\ bond$

b.) The chemical bond that is formed by the transfer of electrons between two atoms is known as an ionic bond.

     Covalent bond is the chemical bond present in an oxygen molecule.
