Final answer:
C4H10 has two isomers: n-butane and isobutane (also known as methylpropane), each with distinct structures and properties.
Step-by-step explanation:
There are two isomers of C4H10, which can be identified by tracing their carbon backbones. When you perform this action on a molecular structure, you will not lift your hand or pencil until you reach the end of the carbon chain.
- The first isomer is n-butane, a straight-chain alkane with the IUPAC name butane. Its structure is CH3CH2CH2CH3.
- The second isomer is isobutane (also known as methylpropane), a branched-chain alkane with the IUPAC name 2-methylpropane. Its structure is (CH3)3CH.
Both of these structures have the same molecular formula C4H10, but their physical arrangements and names are different, leading to different physical and chemical properties.
