- 1-bromo-2-methylbutane
Answer
The reactivity order of abstraction of H atoms towards bromination of alkane is 3°H (tertiary) > 2°H (secondary) > 1°H (primary).
Bromine will be substituted to the Hydrogen where carbon has least number of hydrogen atoms. In this case, methyl group is attached at second position, so only 1 hydrogen is attached to second carbon atom (tertiary).
The correct option is A.
