Choose the correct statement from the following
Options
- ANH ₄⁺ and CH ₄ are not isoelectronic species
- BBF ₃ does not have dipole moment
- CO - Cl - O obeys octet rule
- DO ⁻ in O ₃ is Sp ^3 -hybridised
Correct answer
B. BF ₃ does not have dipole moment
Step-by-step solution
(1) For NH ₄⁺ ; No . of V E =10 For CH ₄ ; No. of V E =10 They are isoelectronic species. (2) (3) O - Cl - O does not follow octet rule. (4)
