Bromine is highly regio selective in where it attacks. The relative rates of attack at the different types of H atom are 3° :2° :1° =1640:82:1 <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-6lkjutkojbaefxvd.jpg" />

Q. When isobutane is treated with $B r_{2}$ in sunlight, then major product is :-

$1^{\circ}$ alkyl bromide

$2^{\circ}$ alkyl bromide

$3^{\circ}$ alkyl bromide

alkene

Bromine is highly regio selective in where it attacks. The relative rates of attack at the different types of H atom are $3^{\circ} : 2^{\circ} : 1^{\circ} = 1640 : 82 : 1$
