Assertion Bond angles of `NH_(3),PH_(3),AsH_(3)` and `SbH_(3)` decrease in order as mentioned
Reasoning The central atom in each possesses a lone pair .

Options

A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`
B. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`
C. If `(A)` is correct but `(R )` is incorrect
D. If `(A)` is incorrect but `(R )` is correct

Answer

B

Explanation

Bond angle of hybrides of group 15 decreases down the group due to increase in size or decrease in `EN` of central atom Thus both `(A)` and `(R )` are correct but `(R )` is not the correct explantion of `(A)` .
