Which of the following statements are correct ?
(a) All the three N___O bond lengths in `HNO_(3)` are equal.
(b) All P___Cl bond lengths in `PCl_(5)` molecule in gaseous state are equal
(c ) `P_(4)` molecule in white phosphrus have angular strain therefore white phosphorus is very reactive
(d) `PCl_(5)` is ionic in solid state in which cation is tetrahedral and anion is octahedral . And anion is octahedral.

Answer

C, D

Explanation

(a) All the three N__O bond lengths in `HNO_(3)` are not equal.
(b) All P___Cl bond lengths in `PCl_(5)` molecule in gaseous state are not equal. Axial bond is longer than equatorial bond.
(c ) `P_(4)` molecule in white phosphorous have angular strain therefore white phosporous is very reactive.
(d) `PCl_(5)` is ionic in soild state in which cation is tetrahedral and anion is octahedral.
Cation - `[PCl_(4)]^(+)`
Anion - `[PCl_(6)]^(-)`
