Draw all possible skeletons for a 7-C compound with(a) A 6-C chain and 1 double bond
Stolb23 [73]

The possible structures with 6-C Chain and 1 double bond i.e. the isomers are                2-methylhex-2-ene , 3-methylhex-2-ene , 4-methylhex-2-ene ,                5-methylhex-2-ene , 2-methylhex-3-ene , 3-methylhex-3-ene ,                  4-methylhex-3-ene , 5-methylhex-3-ene , 2-methylhexene ,                       3-methylhexene  , 4-methylhexene , 5-methylhexene .2-methylene hexane , 3-methylenehexane .

These all are functional group  isomers.

<h3>isomers :</h3>

same molecular formula but different physical and chemical properties .

<h3>Positional isomers :</h3>

same molecular and chemical formula but different in position of the functional group .it is a structural isomerism .

<h3>functional isomers :</h3>

same molecular formula but different functional groups attached to the main ring.
