Question

give two examples each for position and functional isomerism ​

Answer 1

Explanation:

Functional group isomerism

In this variety of structural isomerism, the isomers contain different functional groups - that is, they belong to different families of compounds (different homologous series). For example, a molecular formula C3H6O could be either propanal (an aldehyde) or propanone (a ketone).

Answer 2

Isomerism is the phenomenon in which more than one compounds have the same chemical formula but different chemical structures.

Explanation:

Position isomerism : This type of isomerism arises due to the difference in the position of substituent group or in the position of multiple bond.

example: 1.  CH3-CH2-CH2-CH2-Cl       1 - chloro butane

                CH3-CH-CH2-CH3                 2 - chloro butane

                            |

                          Cl

example: 2. CH3-CH2-C=CH                  1 - butyne

                    CH3-C=C-CH3                    2-  butyne

Functional isomerism : This type of isomerism arises in carbon compounds having the same molecular formula but with different functional groups.

example: 1. CH3-CH2-CH2-OH               1 - proparal(C3H8O)

                   CH3-CH2-O-CH3                  2 - methoxy ethane (C3H8O)

example: 2. CH3-CH2-OH                        1 - ethanol

                    CH3-O-CH3                          2- methoxy methane
