Question

BF3 does not have proton but still acts as an acid and reacts with NH3. Why is it so? What type of bond is formed between the two?

Answer 1

$\huge \mathfrak{Answer:-}$

Total of $\bold{6\:electrons}$ are there.

So,

To have the noble configuration there is a deficiency of $\bold{2\:electrons.}$

Hence,

$BF_{3}$ attains a $\bold{stable\: electronic}$ configuration of 8.

We know that compounds which accept electrons are acidic.

Hence,

$BF_{3}$ behaves as an $\bold{acid.}$

Answer 2

Answer:

Acc. To Lewis acid base theory BF3 will act as an acid n NH3 will be Lewis base n they will form coordinate bond

Explanation:

BF3 has an incomplete octet of a central atom n lewis acid are acceptor of electrons.NH3 has a lone pair besides a complete octet
