The reaction of 1-bromo-3-chlorocyclobutane with metallic sodium in dioxane under reflux conditions gives
Identify Z in the following reaction sequence
CH3CH2CH2OH X → Y
CH3-CH(NH2)-CN2NH2
CH3-CHOH-CH2OH
CH3-C(OH)=CH2
CH3-C≡CH
D.
CH3-C≡CH
CH3CH2CH2OH CH3CH = CH2
Alc. KOHsmoothly brings about dehydrobromination of y to give a mixture of vinyl bromide (A and B) while NaNH2 being a strong base than alcohol KOH readily brings about dehydrobromination of less reactive vinyl bromide to give propyne (Z).
