Chemistry - CHEMICAL BONDING Question with Solution | TestHub
In which of the following species presence of double bond does not affect idealised bond angle :-
(I) (II) (III) (IV)
Options:
Answer:
Solution:
The correct answer is (A) II, III, IV.
In POCl₃, the asymmetric presence of a single P=O double bond exerts stronger repulsion, distorting the bond angles from the idealized .
In XeO₃F₂ (sp³d), the three equatorial oxygen atoms are distributed perfectly symmetrically, preserving the idealized angles of and .
In XeO₂F₄ (sp³d²), the two oxygen atoms are in trans positions, maintaining a highly symmetric octahedral shape with idealized and angles.
In XeO₄ (sp³), all four bonds are identical Xe=O double bonds, forming a perfectly symmetrical tetrahedral geometry with a standard angle.
