Question

Design a synthesis of 1-chloro-2-propanol from 1-propanol.

Choose the best option for the immediate precursor to the target molecule.

An alkene can be used to introduce both an alcohol and a halide functional group to each of the carbons of the double bond in a controlled and predictable manner in one step. 

Choose the best option for the precursor needed to make the alkene.

Answer 1

IN first step during conversion of 1-propanol to 1-bromopropene , simple substitution reaction has been done with HBr and after this , alkyl halide is converted to alkene by use of alcoholic KOH which undergoes elimination mechanism so it eliminates Br^- and forms an alkene .

Now this alkene can be converted to 1-chloro-2-propanol by reacting it with Cl₂ in presence of H₂O

l-chloro-2-propanol from l-propanol This conversion occurs by following step :- ICKO w now, when someone HBY i-Propanol albene (II) + Cla H2O, CH & - CH3-C=CH - > СНs- сн — сно CH-CH=CH2 RYX OH ② OH2 i-Chloro - propanol all Answer, o ist ques = 1 Sed question =
