JEE PYQ: Alcohols Phenols And Ethers Question 18
Question 18 - 2020 (04 Sep Shift 2)
The major product [B] in the following reactions is:
$$\text{CH}_3-\text{CH}_2-\overset{\text{CH}_3}{\underset{|}{\text{CH}}}-\text{CH}_2-\text{OCH}_2-\text{CH}_3 \xrightarrow{\text{HI}/\text{Heat}} [\text{A}] \text{ alcohol} \xrightarrow{\text{H}_2\text{SO}_4/\Delta} [\text{B}]$$
(1) $\text{CH}_2=\text{CH}_2$
(2) $\text{CH}_3-\text{CH}=\overset{\text{CH}_3}{\underset{|}{\text{C}}}-\text{CH}_3$
(3) $\text{CH}_3-\text{CH}_2-\overset{\text{CH}_3}{\underset{|}{\text{C}}}=\text{CH}_2$
(4) $\text{CH}_3-\text{CH}_2-\text{CH}=\text{CH}-\text{CH}_3$
