Based on the compounds of group 15 elements, the correct statement (s) is (are)

Options

A. `Bi_(2)O_(5)` is more basic than `N_(2)O_(5)`
B. `NF_(3)` is more covalent than `BiF_(3)`
C. `PH_(3)` boils at lower temperature than `NH_(3)`
D. The N-N single bond is stronger than the F-F single bond

Answer

A, B, C

Explanation

(a) `Bi_(2)O_(5)` is metallic oxide but `N_(2)O_(5)` is non metallic oxide therefore `Bi_(2)O_(5)` is basic but `N_(2)O_(5)` is acidic.
(b) In `NF_(3)`, N and F are non metals but in `BiF_(3)` , Bi is metal but F is non metal therefore `NF_(3)` is more covalent than `BiF_(3)`.
(c) In `PH_(3)` hydrogen bonding is absent but in `NH_(3)` hydrogen bonding is present therefore `PH_(3)` boils at lower temperature than `NH_(3)`.
(d) Due to small size in N-N single bond l.p. -l.p. repulsion is more than P-P single bond therefore N-N single bond is weaker than the P-P single bond.
