Write the position of principal functional groups ?

Assertion: In the case of polyfunctional compounds, the choice of principal functional group is made on the basis of order of preference. Reason: The order of decreasing priority for some functional group is

Position isomerism is due to the difference in the position of a functional group, multiple bond or substituent in the same carbon chain
