Maelezo
The structural isomers of chlorobutane are: 1-chlorobutane, 2-chlorobutane, 1-chloro-2-methylpropane, and 2-chloro-2-methylpropane; in total, there are four structural isomers of chlorobutane.
Explanation:
- 1-chlorobutane: Chlorine is attached to the first carbon of a straight carbon chain.
- 2-chlorobutane: Chlorine is attached to the second carbon of a straight carbon chain.
- 1-chloro-2-methylpropane: A methyl group is attached to the second carbon of a propane chain, with chlorine on the first carbon.
- 2-chloro-2-methylpropane: Chlorine is attached to a carbon that is also connected to two methyl groups.
