Alcohols Phenols and Ethers - Result Question 8
####8. Consider the following reaction,
[2009]
ethanol $\xrightarrow{PBr_3} X \xrightarrow{\text{ alc. } KOH} Y$
$\xrightarrow[\text{ (ii) } H_2 O \text{, heat }]{\text{ (i) } H_2 SO_4 \text{ rom temperate }} Z$;
the product $Z$ is:
(a) $CH_3 CH_2-O-CH_2-CH_3$
(b) $CH_3-CH_2-O-SO_3 H$
(c) $CH_3 CH_2 OH$
(d) $CH_2=CH_2$
Show Answer
Solution:
- (c)
$ \begin{matrix} CH_3 CH_2 OH \xrightarrow{PBr_3} CH_3 CH_2 Br \xrightarrow{\text{ alc. } KOH} CH_2=CH_2 \\ CH_3 CH_2 OH \stackrel{H_2 SO_4}{\stackrel{H_2 O}{\text{ heat }}} CH_3-CH_2-HSO_4 \end{matrix} $
