Question

How many structures of isomers can you draw for pentane?

Answer 1

Structural isomer:

1. Isomerism in which isomers have various configurations of atoms within the molecule is known as structural isomerism.
2. The chemical formula of the compound remains the same only the physical arrangement is changed.
3. Only three structural isomers exist in the chemical molecule pentane, which is a five-carbon alkane.
4. n-pentane or simply pentane is the first isomer with a straight-chain structure.
5. $2-$methyl butane or iso pentane is the second isomer, which has a branched-chain structure with one carbon atom connected to three other carbon atoms.
6. $2,2-$-dimethylpropane or Neo pentane, is the third isomer and has a branched-chain structure with the core carbon atom connected to four other carbon atoms.

Therefore, there are three structural isomers of pentane.
