(iv) A compound containing an ionic bond

Answer 1

Explanation:

1. CH3 - CH3
2. CH2=CH2
3. CH TRIPLE BOND CH
4. NACL

Answer 2

Explanation:

(i) A molecules containing single covalent bond. - Hydrogen; denoted by ‘H’ has atomic number as 1 and is considered to be the lightest element constituting 75% of all baryonic mass.

(ii) A molecules containing double covalent bond. - Oxygen; denoted by ‘O’ has the atomic number as 8 , is a member of chalcogen group in the period table acts as an oxidizing agent as well as is  a highly reactive metal.

(iii) A molecules containing triple covalent bond. - Nitrogen; denoted by ‘N’ has the atomic number as 7, is an inert gas which is used to reduce or eliminate oxidations of materials and replace air.

(iv) A compound containing an ionic bond. - Chloride: is an ion of Chlorine denoted by ‘Cl’ has the atomic number 17, is considered to be the 2nd lightest element of the halogen group in the periodic table used as an antiseptic agent.
