The four isomers of C4H9Cl are:
- 1-chlorobutane: This compound features a chlorine atom attached to the first carbon of a straight-chain butane.
- 2-chlorobutane: In this isomer, the chlorine is attached to the second carbon of the butane chain.
- 1-chloro-2-methylpropane: Here, one carbon of the butane chain is replaced with a methyl group, and the chlorine is on the first carbon.
- 2-chloro-2-methylpropane: In this isomer, the chlorine is attached to the second carbon, which is also connected to a methyl group, making it a branched compound.
These systematic names reflect the position of the chlorine atom and the structure of each isomer. Understanding the different isomers helps in comprehending the properties and reactivity of each compound.
