An unsaturated organic compound (C\(_3\)H\(_6\)), undergoes the following series of reactions:
\(\text{C}_3\text{H}_6 \xrightarrow{\large{dil\ H_2SO_4}} [\text{B}]\ (\text{Major Product}) \xrightarrow{\large{+\ HCl\ /\ ZnCl_2}} [\text{C}] \xrightarrow{\large{Na_{(s)}\ /\ dry\ ether}} [\text{D}]\)
Identify compound [D]
- A 2,3–dimethylbutane
- B 2-methyl pentane
- C Cyclohexane
- D Hexane
Answer & Solution
Correct Answer
(A) 2,3–dimethylbutane
Step-by-step Solution
Detailed explanation
The unsaturated organic compound \(\text{C}_3\text{H}_6\) is propene, \(\text{CH}_3-\text{CH}=\text{CH}_2\). Hydration of propene with dil. \(\text{H}_2\text{SO}_4\) follows Markovnikov's rule to give propan-2-ol as the major product [B].…
