Question

Is 2,5-dibromohexane chiral? If chiral, give the atom number(s) of the chirality center(s) (increasing numberical order, separated by a comma, no space). Write 'none' if there are no chirality centers. . Is 1-bromo-3-chloro-2-methylpropane chiral? If chiral, give the atom number(s) of the chirality center(s) (increasing numberical order, separated by a comma, no space). Write 'none' if there are no chirality centers.

Answer 1

2,5-Dibromohexane has two chiral centers, and 1-bromo-3-chloro-2-methylpropane has one chiral center.

Step-by-step explanation:

To determine if a molecule is chiral, we need to check if it has a chiral center. A chiral center is a carbon atom that is bonded to four different groups. In 2,5-dibromohexane, both carbon atoms in the middle of the chain have four different groups, meaning it has two chiral centers.

In 1-bromo-3-chloro-2-methylpropane, the carbon atom bonded to the bromine, chlorine, and methyl groups is a chiral center, meaning it has one chiral center.

Therefore, the answer to the first question is 2,5-dibromohexane has two chiral centers, and the answer to the second question is 1-bromo-3-chloro-2-methylpropane has one chiral center.
