reaction [1] 54.2079 Set H Q.No. 20 OR:-

An unsaturared hydrocarbon (C3H6) undergoes Markovnikov's rule to give (A). Compound (A) is hydrolysed with aqueous alkali to yield (B). When (B) is treated with PBr3, compound (C) is produced. (C) reacts with AgCN (alc.) to give another compound (D). The compound (D) if reduced with LiAlH4, produce (E).
i. Define Markovnikov's rule.
ii. Identify (A), (B), (C), (D) and (E) with chemical reaction.
iii. How does E react with nitrous acid? iv.How would you convert (B) into C3H8? [1+5+1+1]​
