The reaction condition leading to the best yield of C 2 H 5 Cl are
Options
- AC 2 H 6 ( excess ) + C l 2 → U V l i g h t
- BC 2 H 6 + C l 2 ( excess ) → r o o m     t e m p . d a r k
- CC 2 H 6 + C l 2     → U V     l i g h t
- DC 2 H 6 + C l 2 ( excess ) → U V l i g h t
Correct answer
A. C 2 H 6 ( excess ) + C l 2 → U V l i g h t
Step-by-step solution
During chlorination of alkane, if excess of alkane is treated with Cl 2 ( g ) in presence of light or heat, chance of mono–chlorination predominant. C 2 H 6 ( excess ) + C l 2 → U V l i g h t CH 3 C H 2 C l + H C l
