Question

Which has same hybridised?  

(a) AlCl₃, [AlCl₄]^- 

(b) BF₃, [BF₄]^- 

(c) NH₃, [NH₄]⁺ 

(d) \(\overset{+}{N}O_2\) , \(\overset{-}{N}O_2\)

Answer 1

(a) AICI₃ − It has sp² hybridisation. 

[AICI₄]⁻ − It has sp³ hybridisation. 

(b) BF₃ − It has sp² hybridisation. 

[BF₄]⁻ − It has sp³ hybridisation.

(c) NH₃ − It has sp³ hybridisation. 

[NH₄]⁺ − It has sp³ hybridisation. 

(d) \(\overset{+}NO_2\) − It has sp hybridisation. 

\(\overset{-}NO_2\) − It has sp² hybridisation.

So, choice (c) NH₃ and [NH4]⁺ have same hybridisation.
