The majorproduct obtained in the photo catalysed bromination of 2-methylbutane is :

Answer»

1-bromo-2-methylbutane
1-bromo-3-methylbutane
2-bromo-2-methyl butane
2-bromo-2-methyl butane

Solution :The ORDER of substitution in different alkanes is
`3^(@) GT 2^(@) gt 1^(@)`
Thus the bromination of 2-methy lbutane MAINLY gives 2-Bromo-2- methyl butane
`CH_(3)-underset(2-"methylbutane")(CH_(2))-overset(CH_(3))overset(|)(CH)-CH_(3) overset(Br_(2))to`
