Question

what is chain isomerism?

Answer 1

Answer :-

Chain isomerism arises due to the difference in the arrangement of carbon chain within the molecule. In other words, if two compounds with the same molecular formula have a different main chain, then they exhibit chain isomerism.

Answer 2

$\huge\sf\colorbox{plum}{Answer}$

• Chain isomers have the same molecular formula, but the way their carbon atoms are joined together differs from isomer to isomer. Alkane molecules with four or more carbon atoms have chain isomers. In these isomers, the carbon atoms are bonded together in different ways to produce branches.
• . For example, there are two isomers of butane, C4H10. In one of them, the carbon atoms lie in a straight chain whereas in the other the chain is branched.
