Question

The major product obtained in the photo-catalyzed bromination of $2$-methyl butane is:

• A. $2$-bromo-$2$-methylbutane
• B. $2$-bromo-$3$-methylbutane
• C. $1$-bromo-$2$-methylbutane
• D. $1$-bromo-$3$-methylbutane

Answer 1

The correct option is A $2$-bromo-$2$-methylbutane

R.E.F image

(major)(2$-$bromo$-$2$-$methylbutane)

$\to$ Major product is obtained by replacing $3^{\circ }-$ Hydrogen because $3^{\circ }$ radicle is stable more.

Hence, the correct option is A.
