Question

Identify the Lewis acid in this balanced equation: Central N is bonded above, left, and below to C H 3 and has 2 electron dots to the right. Plus. B is bonded above, below left, and below right to H. Right arrow. N superscript plus is bonded above, below, and left to C H 3, and to the right to B; the B is bonded above, below and right to H. N(CH3)3 BH3 (CH3)3N:BH3.

Answer 1

A chemical substance that gains or accepts electrons from others is called lewis acids. The Lewis acid in the reaction is Trihydridoboron $(\rm BH_{3}).$

What are lewis acids and bases?

For the formation of the covalent bonds the molecule or the atoms that accept or gain an electron from the other species present in the reaction are called lewis acids. The species formed after accepting electrons are called a conjugate base.

The species that donates electrons to the other species are called lewis base and the species formed after the electron donation is called a conjugate acid.

Therefore, option B. $\rm BH_{3}$ is the lewis acid as it gains an electron.
