Question
Which of the following statements are correct?
(i) All the three N – O bond lengths in \[\ce{HNO3}\] are equal.
(ii) All P – Cl bond lengths in \[\ce{PCl5}\] molecule in gaseous state are equal.
(iii) \[\ce{P4}\] molecule in white phosphorus have angular strain therefore white phosphorus is very reactive.
(iv) \[\ce{PCl}\] is ionic in solid state in which cation is tetrahedral and anion is octahedral.
Solution
(iii) \[\ce{P4}\] molecule in white phosphorus have angular strain therefore white phosphorus is very reactive.
(iv) \[\ce{PCl}\] is ionic in solid state in which cation is tetrahedral and anion is octahedral.
Explanation:
The \[\ce{P4}\] molecule in white phosphorus has an angular strain, white phosphorus is very reactive.
\[\ce{PCl5}\] is ionic in the solid-state, with a tetrahedral cation and an octahedral anion.
