Statement I : In vinyl chloride , the bond involves an hybridized carbon, while in ethyl chloride , it involves an carbon. The carbon has greater s-character, forming a shorter and stronger bond. Additionally, resonance stabilization from the Cl atom's p -orbital overlapping with the system further strengthens the vinyl bond. Statement I is TRUE.

Statement II: The optically active molecule shown has a stereogenic center bearing , and Cl groups. Upon hydrolysis via nucleophilic substitution (typically SN1 for tertiary or secondary centers), the C-Cl bond breaks to form an alcohol. SN1 mechanism generates a carbocation intermediate, allowing nucleophilic attack from both faces, producing a racemic mixture of the alcohol product. A racemic solution cannot rotate polarized light as the d- and l-enantiomers cancel each other's rotations. Statement II is FALSE.
