Question

class 12th organic chemistry conversions

1. butan-2-ol to 3-methylpentan-3-ol

2. 2-chloro-2,3-dimethylbutane to acetone​

Answer 1

Answer:

To prepare 3-methylbutan-2-ol from 3-methylbut-1-ene shouls involve Markovnikov's addition of H−OH across double bond

A. Addition of water in presence of dil. H

follows Markovnikov's addition of H−OH across the alkene

B. Addition of HCI followed by reaction with dil. NaOH to an alkene can give substitution and elimination product after alkyl halide formation

C. Hydroboration-oxidation reaction follows Anti-Markovnikov's addition of H−OH

D.Reimer - Tiemann reaction.is a chemical reaction used for the ortho-formylation of phenols

Thus the best method to prepare 3-methylbutan-2-ol from 3-methylbut-1-ene is the addition of water in presence of dil. H
