Statement: Acidic nature of boron trihalides is in the order `BF_(3)ltBCI_(3)ltBBr_(3)ltBI_(3)`.
Explanation: Basic nature of nitrogen trihalides is in the order `NF_(3)gtNCI_(3)gtNBr_(3)gtNI_(3)`.

A

S is correct but E is wrong.

B

S is wrong but E is correc.

C

Both S and E are correct and E is correct explanation of S.

D

Both S and E are correct but E is correct explanation of S.

Text Solution

Verified by Experts

The correct Answer is:
A
Statement is correct due to back-bonding in boron. In nitrogen halides, the order is `NF_(3)ltNCI_(3)ltNBr_(3)ltNI_(3)` on account of decreasing electronegativity of halogents. In `NF_(3)`, the lone pair is not released easily due to more `+ve` charge on N.
