An alkyl halide `(X)`of the folmula `C_(6)H_(13)Cl` on treatment with potassium tertiary butoxide gives two isomeric alkenes `(Y)` and `(Z)(C_(6)H_(12))`. Both the alkenes on hydrogenation give `2,3-`dimethyl butane. Perdict the structures of `(X),(Y)` , and `(Z)`

Answer

(x) `CH_(3)-underset(Cl)underset(|)overset(CH_(3))overset(|)C-overset(CH_(3))overset(|)CH-CH_(3)`
(Y) `CH_(2)=overset(CH_(3))overset(|)C-overset(CH_(3))overset(|)CH-CH_(3)`
(Z) `CH_(3)-overset(CH_(3))overset(|)C=underset(CH_(3))underset(|)C-CH_(3)`
