Question

Pcl5 in gaseous state. (b) peroxymonosulphuric acid ( h2so5) (c ) xeof4

Answer 1

It’s largely the size of chlorine: it’s a fair bit bigger than fluorine. Bonds to chlorine are also weaker, so there’s more incentive to disproportionate from molecular PCl5 (the gas phase composition of PCl5).
