CAIE A-Level Chemistry A2 33.3.4 Hydrolysis Reactivity Acyl Vs Alkyl Chlorides Topic Practice

chlorobenzene is less reactive than ethanoyl chloride

- p orbital / lone pair on Cl/ -Cl will overlap / delocalise into the ring

OR C of COCl has most electron deficient OR has an electronegative oxygen atom / two electronegative atoms / electron withdrawing C=O group

- due to partial double C-Cl bond

OR C-Cl bond strengthened (more) / stronger bond between Cl and benzene / ring

OR C-Clweakened in ROCl

any two [1], all three [2]
