The final product (IV) in the sequence of reactions \[\begin{align}   & C{{H}_{3}}CHOH\xrightarrow{PB{{r}_{3}}}I\xrightarrow[Ether]{Mg} \\  & | \\  & C{{H}_{3}} \\ \end{align}\]                              ..

A)           \[\begin{align}   & C{{H}_{3}}-CHOC{{H}_{2}}C{{H}_{2}}OH \\  & | \\  & C{{H}_{3}} \\ \end{align}\]

B)             \[\begin{align}   & C{{H}_{3}}-CHC{{H}_{2}}C{{H}_{2}}Br \\  & | \\  & C{{H}_{3}} \\ \end{align}\]

C)              \[\begin{align}   & C{{H}_{3}}-CH-C{{H}_{2}}C{{H}_{2}}OH \\  & | \\  & C{{H}_{3}} \\ \end{align}\]

D)               \[\begin{align}   & C{{H}_{3}}-CHOC{{H}_{2}}C{{H}_{3}} \\  & | \\  & C{{H}_{3}} \\ \end{align}\]

Correct Answer: C

Solution :

                \[{{i}_{1}}=\frac{15}{1}mA=15mA\]                      \[R=250\Omega \]
