Answer 1

Answer :

B

Solution :

Carboxylic acids never exhibit position isomersm because −COOH function always located at C−1 of the chain.

(1) 1,3-dioxacyclohexane and 1,4-dioxacyclohexane

(2) Butan-1-ol and butan-2-ol

(4) 1-Methoxy-2-methylpropane and 2-methoxy-2-meth-ylpropane

To avoid any possible cunfusion, it is always adivised to write down the complete strutural formula.

Please mark me Brainliest

Explanation:

The compound that have same molecules formula but differ in the position of functional group, C−C multiple bond, or substituent group are called position isomers.

→  But −1−ene and But −2−ene are positional isomers.

→  Pentane−2−oic acid and Hexanoic acid have different position of −COOH group but same molecular formula.

→  2−nitrile propane and Butane nilrile are also positional isomers.
