In which of the following species, bonding is taking place in excited state ?

A

`BeCl_(2)(g)`

B

`C Cl_(4)`

C

`NF_(3)`

D

`PCl_(5)`

Text Solution

Verified by Experts

The correct Answer is:

A, B, D

In `NF_(3)` bonding is takaing place in ground state (Since number of bonds formed by the central atom `=` number of unpaired electrons on centeral atom in ground state).
In all other species, bonding is taking place in excited state (Since number of bonds formed by the central atom `gt` number of unpaired electrons on central atom in ground state).
