Options

• 3

• 4

• 1

• 2

Answer 1

The number of possible monohalogen derivatives for the alkyl halide having molecular formula C₄H₉X is 4.

Explanation:

Monohalogen derivatives for C₄H₉X are

1. \[\ce{CH3 - CH2 - CH2 - CH2 - X}\]

2. \[\begin{array}{cc}
\ce{CH3 - CH2 - CH - CH3}\\
\phantom{......}|\\
\phantom{......}\ce{X}
\end{array}\]

3. \[\begin{array}{cc}
\phantom{.....}\ce{CH3}\\
\phantom{...}|\\
\ce{CH3 - C - X}\\
\phantom{...}|\\
\phantom{.....}\ce{CH3}
\end{array}\]

4. \[\begin{array}{cc}
\ce{CH3 - CH - CH3}\\
|\phantom{..}\\
\phantom{.....}\ce{CH2 - X}
\end{array}\]
