Which one of the following conversions involve change in both hybridisation and shape?

A

`CH_(4)rarrC_(2)H_(6)`

B

`NH_(2)rarrNH_(4)^(+)`

C

`BF_(3)rarrBF_(4)^(-)`

D

`H_(2)Orarr H_(3)O^(+)`

Text Solution

Verified by Experts

The correct Answer is:
C
In `BF_(3)`, hybridisation of B is `sp^(2)` and its geometry is trigonal planar. In `BF_(4)^(-)`, the hybridisation of B is `sp^(3)` and its geometry is tetrahedral.
