Question

double bond isomers examples​

Answer 1

Answer:

There are three types of structural isomers: chain isomers, functional group isomers and positional isomers. Chain isomers have the same molecular formula but different arrangements or branches. Functional group isomers have the same formula but different functional groups.

Hope it helps you!!!

Answer 2

Answer:

We could name it 2-butene, but there are actually two such compounds; the double bond results in cis-trans isomerism. Cis-2-butene has both methyl groups on the same side of the molecule. Trans-2-butene has the methyl groups on opposite sides of the molecule as shown in the diagram below.
