Detailed explanation-1: -What operation would transform 2, 2 dimethylbutane into hexane? Adding one carbon and three hydrogen atoms.
Detailed explanation-2: -Hexane and 2, 3-dimethylbutane are chain isomers. They both have the same number of carbon and hydrogen atoms but in hexane these are arranged in one long chain whereas 2, 3-dimethylbutane has some carbon atoms coming off the main chain as side branches.
Detailed explanation-3: -2, 2-Dimethylbutane, trivially known as neohexane, is an organic compound with formula C6H14 or (H3C-)3-C-CH2-CH3. It is therefore an alkane, indeed the most compact and branched of the hexane isomers-the only one with a quaternary carbon and a butane (C4) backbone.
Detailed explanation-4: -Both have the same carbon chain but position of substituents are different. So, they are positional isomers.
Detailed explanation-5: -2, 3-dimethylbutane and 2-methylpentane : Both the molecules have the same molecular formula C6H14 C 6 H 14 . So, they are structural isomers.
