Question

Write the structural formulae of all isomers of hexane.

Answer 1

Hexane has the following five isomers
(i) `CH_(3)-underset("n-hexane")(CH_(2)-CH_(2))-CH_(2)-CH_(2)-CH_(3)`
(ii) `overset(1)CH_(3)-underset("2-methyl pentane")underset(CH_(3))underset(|)(overset(2)CH)-overset(3)CH_(2)-overset(4)CH_(2)-overset(5)CH_(3)`
(iii) `overset(1)CH_(3)-underset("3-methyl pentane")(overset(2)CH_(2)-underset(CH_(3))underset(|)overset(3)CH)-overset(4)CH_(2)-overset(5)CH_(3)`
(iv) `underset("2,3-dimethyl butane")(overset(1)CH_(3)underset(CH_(3))underset(|)(-overset(2)CH)underset(CH_(3))underset(|)(-overset(3)CH-)overset(4)CH_(3))`
(v) `underset("2,3-dimethyl butane")(overset(1)(C)H_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(overset(2)(C))-overset(3)CH_(2)-overset(4)CH_(3)`
