Question:medium

Sulphur dioxide on reaction with chlorine in the presence of charcoal gives compound (A). This on reaction with white phosphorus gives SO\(_2\) and compound (B). The correct statement about 'B' is

Show Hint

The structures of phosphorus pentahalides are important. Remember that PCl\(_5\) is molecular (trigonal bipyramidal) in gas/liquid phase, but ionic ([\(PCl_4\)]\(^+\)[\(PCl_6\)]\(^-\)) in the solid state. PBr\(_5\) is also ionic ([\(PBr_4\)]\(^+\)Br\(^-\)) in the solid state.

Updated On: Mar 30, 2026

The shape of 'B' is pyramidal
'B' on hydrolysis gives phosphorus acid
'B' in solid state exists as an ionic solid
In 'B' all bonds are equivalent

Show Solution

The Correct Option is C
