Question

Hybridisation in CH₃ , CH₃ and CH₃ are respectively

(a) sp², sp², sp³

(b) sp², sp³, sp³

(c) sp³, sp³, sp²

(d)  sp³, sp^2, sp³

Answer 1

Correct option (a) sp², sp², sp³

Explanation:

CH₃ (methyl free radical) has planar structure with sp² hybridisation of 'C' atom. The odd electron is present in unhybridised 2p_z orbital.

(methyl carbonium ion) also has trigonal planar structure (sp²).

(methyl carbanion) has tetrahedral structure (sp³) and one of the hybrid orbitals contains the lone pair of electrons.
