(B) 2 - bromo 3 - methylbutane
(C) 1 - bromo 2-methylbutane

Answer 1

Answer:

Question No. 66

The major product obtained in the photo - catalysed bromination of 2-methylbutane is

(B) 2 - bromo 3 - methylbutane

Answer 2

The major product obtained in the photo-catalyzed bromination of 2-Methylbutane is 2-Bromo-2-methylbutane.

• Photo - catalysed bromination reaction involves radical mechanism.
• Hence, in the given reaction, the radical is formed at the second carbon due to the formation of the stable tertiary radical.
• As a result, the bromo radical attacks at this position and forms 2 - bromo 2-methylbutane as the major product.
