✓
$C{H_3} - CH = C{H_2}\mathop {\xrightarrow{{{B_2}{H_6}}}}\limits_{O{H^ - }} $
B
$C{H_3}C{H_2}C{H_2}I\mathop {\xrightarrow{{HI}}}\limits_P $
C
$C{H_3}C{H_2}C{H_2}Cl\xrightarrow{{Na}}$
D
None of these

Answer

Correct option: A.

$C{H_3} - CH = C{H_2}\mathop {\xrightarrow{{{B_2}{H_6}}}}\limits_{O{H^ - }} $

a
(a) Hydroboration of alkenes followed by hydrolysis in basic medium yield alcohols and not the alkanes.

$R - CH = C{H_2}\xrightarrow{{{B_2}{H_6}}}{(R - C{H_2} - C{H_2})_3} - B$ $\xrightarrow{{O{H^ - }}}R - C{H_2} - C{H_2}OH$
