Two students Rehan and Ananya were given the same compound, alkyl halide ($\mathrm{C_2H_5Cl}$) by their chemistry teacher and asked to perform different reactions.
1. Rehan was instructed to use alcoholic KCN as a reagent and Ananya was instructed to use alcoholic AgCN.
2. Rehan observed a compound was formed that could be converted to a carboxylic acid on hydrolysis but Ananya could not obtain the same acid.
3. The teacher explained that the difference was due to the bonding behaviour of cyanide ions in the reagents.
Write the IUPAC names of the compounds formed by Rehan and Ananya.
Answer
Answer
AIRehan: $\mathrm{CH_3CH_2CN}$, propanenitrile (hydrolyses to propanoic acid).
Ananya: $\mathrm{CH_3CH_2NC}$, ethyl isocyanide (isocyanoethane).
