Isomerism
1 Structural isomerism
1.1 chain isomerism
1.1.1 same functional gp
1.1.2 structural isomers that differ in the length of the main carbon chain
1.2 Position isomerism
1.2.1 differ only in the position of the functional group
1.2.2 same functional gp
1.3 Functional Group isomerism
1.3.1 belongs to different homologous series
2 Stereoisomerism
2.1 cis-trans isomerism
2.1.1 when there is C=C double bond, rotation is restricted
2.1.2 CIS-
2.1.2.1 same side
2.1.2.2 has net dipole moment
2.1.2.2.1 a slightly more polar molecule
2.1.2.2.2 higher boiling point
2.1.3 TRANS-
2.1.3.1 Opposite side
2.1.3.2 no net dipole moment
2.1.3.2.1 non-polar
2.1.3.2.2 lower boiling point
2.2 Enatiomerism
2.2.1 image is not superimposable
2.2.2 a carbon atom bonded to 4 different atoms / functional groups
