हिन्दीIdentify the final product [D] obtained in the following sequence of reactions. \( \text{CH}_3\text{CHO} \xrightarrow[ii) \text{H}_3\text{O}^+]{i) \text{LiAlH}_4} [A] \xrightarrow[\Delta]{\text{H}_2\text{SO}_4} [B] \xrightarrow{\text{HBr}} [C] \xrightarrow{\text{Na/dry ether}} [D] \)
Correct answer · Option 2
\( \text{C}_4\text{H}_{10} \)
Explanation
CH3CHO reduces to ethanol [A], dehydrates to ethene [B], reacts with HBr to give bromoethane [C], and Wurtz reaction on bromoethane gives butane (C4H10) [D].
