Question

Assertion : R₃P = O exists but R₃N = O does not exist.

Reason : P is more electronegative than N.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

The correct option is (c) A is true but R is false.

Explanation:

Due to small size and absence of d-orbital, N cannot form R₃N = O. The electronegativity of N (3.0) is much higher than P (2.1).
