Web€€€€€€€€€ (a)€€€€ Describe how propanal, CH3CH2CHO, and propanone, CH3COCH3, can be distinguished using (i)€€€€€ a chemical test and (ii)€€€€ the number of peaks in their proton n.m.r. spectra. (5) 1 ... €€€€ Outline a mechanism for the reaction of CH3CH2CH2CHO with HCN and name the product. WebThis special reaction is a nucleophilic addition, where the nucleophilic CN - attacks the electrophilic carbonyl carbon on the ketone, following a protonation by HCN, thereby the cyanide anion being regenerated. This reaction is also reversible. Cyanohydrins are also intermediates for the Strecker amino acid synthesis.
