Incorrect statement regarding `BF_(3)NH_(3)` molecule is :

Options

A. FBF bond angle `lt120^(@)`
B. HNH bond angle `gt109^(@)28'`
C. Exhibits intermolecular H-bond
D. hybridization of N-atom is `sp^(3)`

Answer

D

Explanation

*Both boron and nitrogen are `sp^(2)`-hybridised.
*FBF bond angle `lt120^(@)` (VSPER theory)
*HNH bond angle is less than `120^(@)` but greater than `109^(@)28.` due to back bonding.
*Due to presence of H-atom attached to nitrogen this molecule can exhibits intermolecular H-bonding.
