The question consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses:
Assertion: `NF_3` is weaker ligand than `N(CH_3)_3`.
Reason: `NF_3` ionizes to give `F^(-)` ions in aqueous solution.

A

If the both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true and the reason is not the correct explanation of the assertion

C

If assertion is true but reason is false

D

If both assertion and reason are false statements.

Text Solution

Verified by Experts

The correct Answer is:
C
Due to high electronegativity of F-atoms, the lone pair of N-atom in `NF_3` molecule cannot be ligated easily.

Except, nitrogen flouride, all other halides hydrolyse in water.
`NCl_3+3H_2O to NH_3+3HClO.`
