Overview

Erudition is an institute which aims at helping the students, keep a balance between scoring good marks and gathering knowledge.
We help the students in strengthening the concepts, by interacting with them. This teacher-student interaction is also a point which makes us different from other institutes.
We don't teach in batches; we teach the students in flocks (very small groups), which helps our faculties to get in personal interactions with all of them.
We provide study materials that help the students sum up the things taught in class, to score good marks.
Though we clear the doubts of the students as much as we can, still, we conduct a doubt clearing session every month, where the students can bring all the doubts that he/ she has faced in that month.

Why do boron halides form addition compounds with NH3?

Boron halides being lewis acids are electron deficient and also electron seeking. Ammonia or amines have an extra lone pair on the nitrogen present as their central atom. That is why boron halides form addition compounds with amines as well as ammonia.

answer to the first question 

Anhydrous AlCl3 is a lewis acid as the Al has its sextet fulfilled. This makes the compound electron loving. In many organic reactions it is used to separate  compounds like Cl2 into Cl+ and Cl- which would help in the aromatic electrophillic substitution, which otherwise would have formed Cl free radical owing to homolytic fission.
