Q. Acid catalyzed hydration of alkenes except ethene leads to the formation of

UPSEEUPSEE 2007

Solution:

$CH_2 = CH_2 \xrightarrow{H_2O/H^+}\underset{1^{\circ}\text{ alcohol}}{CH_3CH_2OH}$
$CH_3 - CH = CH_2 \xrightarrow{H_2O/H^+}$image
$2^{\circ}$ alcohol through $2^{\circ}$ carbocation
$(CH_3\overset{\oplus}{C}HCH_3)$
image
$3^{\circ}$ alcohol through $3^{\circ}$ carbocation $[(CH_3)_3\overset{\oplus}{C}]$
image
image
image
Thus best alternate is $(c)$.
