Question

isomerism of alkens ​

Answer 1

Answer:

When a carbon is bonded to more than two other carbons, a branch is formed. The smallest branched alkane is isobutane. Notice that isobutane has the same molecular formula, C4H10, as n-butane but has a different structural formula. Two different molecules which have the same molecular formula are isomers

Answer 2

For example, the alkene of molecular formula C 4H 8 has two isomers. Stereoisomers. In addition to structural isomers, alkenes also form stereoisomers. Because rotation around a multiple bond is restricted, groups attached to the double‐bonded carbon atoms always remain in the same relative positions.
