JEE Main 2026 — 21 January, Evening Shift — Question 59

Given below are four compounds:

(a) n-propyl choride

(b) iso-propyl chloride

(d) neo-pentyl chloride

Percentage of carbon in the one which exhibits optical isomerism is:

2-Chlorobutane is optically active and chiral molecule

Molecular formula $\Rightarrow \mathrm{C}_{4} \mathrm{H}_{9} \mathrm{Cl}$

Molar mass $=48+9+35.5=92.5$

$\% \mathrm{OC}=\frac{48}{92.5} \times 100=51.89 \%$
