How can acetaldehyde be prepared from acetyl chloride? Propanal is more reactive than propanone towards nucleophilic addition reaction. Give reason.

(a)Acetyl chloride is hydrogenated over catalyst, palladium-barium sulphate to prepare acetaldehyde / (b)Due to less steric hinderance and greater electrophilicity of carbonyl carbon in propanal than propanone. / Due to more steric hinderance and less electrophilicity of carbonyl carbon in propanone than propanal
