Question

What is position isomerism with example in chemistry 1?

Answer 1

Explanation:

positional isomerism:

It occurs when a functional group is in different positions in same carbon chain

Answer 2

Answer:

The phenomenon in which different compounds having the same functional groups at different positions on the parent chain is known as position isomerism.

For example,

But-2-ene [CH_3 -CH=CH-CH_3]

and but-1-ene (CH_2 = CH – CH_2 - CH_3] are position isomers of each other as they have the same molecular formula C_4 H_8 and the same carbon skeleton but the double bonds are located at different positions.
