Quizplus · Accepted Answer

The parent chain is the longest continuous chain with the highest priority functional group (in this case, an alkane). The parent chain in the given structure is a butane chain, as indicated by the "TB" at the end of the name.

The groups on the butane chain from left to right are:
1. An isopropyl group (2-methylpropan-)
2. An isobutyl group (2-methylpropyl-)
3. A sec-butyl group (1-methylpropyl-)

Therefore, the correct choice is B, which lists the groups in the correct order from left to right.
