Is there any change in the hybridisation of B and N atoms as a result of the following reaction?
` BF_3 + NH_3 to F_3 B.NH_3`

Explanation

To determine if there is any change in the hybridization of boron (B) and nitrogen (N) atoms as a result of the reaction \( BF_3 + NH_3 \rightarrow F_3B.NH_3 \), we need to analyze the hybridization of both atoms before and after the reaction.

### Step 1: Determine the Hybridization of Boron in \( BF_3 \)

1. **Identify the Valence Electrons**: Boron (B) has 3 valence electrons.
2. **Count the Attached Atoms**: In \( BF_3 \), boron is bonded to 3 fluorine (F) atoms.
3. **Calculate the Steric Number**:
