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)`

An alkyl halide (A) of formula C_(6)H_(11)CI on treatement with potassium tertiary butoxie gives two isomeric alkenes (B) and (C) C_(6)H_(10) . Both alkene on hydrogenation give methycyclopentane. Predict the structure of (A), (B) and (C).

An alkyl halide of formula C_6 H_13 Br on treatment with potassium t-butoxide gives two isomeric alkenes dimethy butane. Isomeric alkene are :

An alkene (C_(6)H_(12)) is optically active.This on reductive oxonolysis gives

No. of structural isoneric alkenes (molecular formula =C_(6)H_(12) ) which all give n-hexane on hydrogenation in presence of metal catalyst

An aromatic kentone (X) has the molecular formula C_(10)H_(12)O_(2) . On vigorous oxidation, it yields a dibasic acid (Y) having the formula C_(9)H_(8)O_(5) which rapidly forms an anhydride on heating. (X) on strong heating with sodium hypobromite gives monobasic acid (Z) with the formula C_(9)H_(10)O_(3) . (Z), when heated with soda lime, gives 3-methylanisole. Interpret the above reactions and deduce the structures of (X), (Y), and (Z).
