CH 4

SF 4

Text Solution

Verified by Experts

The correct answer is:

For neutral molecules,

No. of electron pairs = No. of atoms bonded to it + 1/2 [Gp. no of central atom – Valency of central atom]

∴ For CH 4 , no. of e – pairs = = 4 (sp 3 hybridisation)

For SF 4 , no. of e – pairs = = 5 (sp 3 d hybridisation)

For ions,

No. of electron pairs = No. of atoms bonded to it + 1/2 [Gp. no. of central atom – Valency of central atom ± No. of electrons]

∴ For BF 4–, no. e – pairs = = 4 (sp 3 hybridisation)

For NH +4 , no. of e – pairs = = 4 (sp 3 hybridisation)
