Show Hint
\(\mathrm{LiAlH_4}\) attacks less substituted carbon of unsymmetrical epoxides.
Updated On: Apr 23, 2026
- (a)
- (b)
- (c)
- (d)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
\[ \mathrm{LiAlH_4} \rightarrow \mathrm{H^-} \text{ nucleophile} \]
Step 2: Calculation / Simplification}
Unsymmetrical epoxide opening follows \(S_N2\) at less hindered carbon.
\(\mathrm{H^-}\) attacks terminal \(\mathrm{CH_2}\) carbon.
Ring opens forming alkoxide on secondary carbon.
Protonation yields \(\mathrm{CH_3CH(OH)CH_3}\) (Propan-2-ol).
Step 3: Final Answer
\[ \mathrm{CH_3CH(OH)CH_3} \]
