MCQ
An organic compound $^1C{H_3}{ - ^2}C{H_2}{ - ^3}C{H_2}{ - ^4}C{H_2}{ - ^5}C{H_2}{ - ^6}C{H_2}{ - ^7}C{H_3}$

To make it chiral compound the attack should be on which carbon atom

  • A
    $1$
  • $3$
  • C
    $4$
  • D
    $7$

Answer

Correct option: B.
$3$
b
${ }^1 CH _3-{ }^2 CH _2- ^3CH _2-{ }^4 CH _2-{ }^5 CH _2-{ }^6 CH _2-{ }^7 CH _3$

$CH _3- CH _2- CH _2- CH _2- CH _2- CH _2- CH _3$

If we substitute third carbon's hydrogen with another group ' $x$ '. The resultant compound will be chiral.

$\begin{matrix} H  \\ |  \\ C{{H}_{3}}-C{{H}_{2}}-{{C}^{*}}-X\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,  \\ |  \\ \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,C{{H}_{2}}-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{3}}  \\ \end{matrix}$
