Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The reaction between Boron trifluoride (BF₃) and Trimethylamine (N(CH₃)₃) forms a Lewis acid-base adduct where a coordinate bond is established between the Nitrogen and Boron atoms.

In this product:

The Boron (B) atom changes from sp² to sp³ hybridization.

The Nitrogen (N) atom retains its sp³ hybridization.

The three Carbon (C) atoms within the methyl groups are also sp³ hybridized.

Since all five of these atoms are non-terminal (bonded to more than one other atom), the total number of sp³ hybridized non-terminal atoms is 5.
