Question

an alkyl halide(A) of formula C6 H13 Cl on treatment with alcoholic KOH gives two isomeric (B)and (c) (C6H12) .both alkenes on hydrogenayion gives 2,3-dimethyl butane. predict the structure of A,BandC . write the reactions involve​

Answer 1

Explanation:

$C_6H_{13}Cl\overset{alc,KOH}\rightarrow$

$CH_3-CH(CH_3)-C(CH_3)=CH_2+CH_3-C(CH_3)=C(CH_3)-CH_3$

Structure of B:2,3 dimethy but-2-ene

$CH_3-CH(CH_3)-C(CH_3)=CH_2\overset{H_2}\rightarrow CH_3CH(CH_3)-CH(CH_3)-CH_3$

Structure of C:2,3 dimethy but-1-ene

$CH_3-C(CH_3)=C(CH_3)-CH_3\overset{H_2}\rightarrow CH_3CH(CH_3)-CH(CH_3)-CH_3$

Structure of A: 2-chloro-2,3-dimethyl butane

$CH_3-CH(CH_3)-CCl(CH_3)-CH_3$
