24 Explain functional group isomerism and position isomerism with exampie.ith exampleSECTION-D

Answer»

Positional isomerism is when you have two compounds with the same molecular formula, where the SAME functional group is located in different positions of a carbon chain.

2-propanol [CH3-CH(OH)-CH3] and 1-propanol [CH3-CH2-CH2-OH] are positional isomers because the alcohol group is in different positions, but the two compounds have the same molecular formula - C3H8O.

Functional isomers are two compounds with the same molecular formula, where two DIFFERENT functional groups are present in the molecule.

2-propanol [CH3-CH(OH)-CH3] and methyl ethyl ether [CH3-O-CH2-CH3] both have the same molecular formula, C3H8O, but are functional isomers.
