Solution
The correct options are
A
B
C
Chain, nuclear or skeleton isomerism: This type of isomerism arises due to the difference in the nature of the carbon chain (i.e., straight or branched) which forms the nucleus of the molecule.
CH3−CH2−CH2−CH2−CH2−CH3 [Hexane]
The possible structures with same molecular formula with only difference in the nature of carbon chain will be:
CH3−CH|CH3−CH2−CH2−CH3
CH3−CH2−CH|CH3−CH2−CH3
CH3−CH3|CH−CH|CH3−CH3
CH3−CH3|C|CH3−CH2−CH3
Hence only nature of carbon chain is changing. But in
CH3−CH3|C|CH3−CH3
No. of carbon = 5
So, molecular formula is changed.
