Question

Identify correct statement from the following:

A. Propanal and propanone are functional isomers.

B. Ethoxyethane and methoxypropane are metamers.

C. But-2-ene shows optical isomerism.

D. But-1-ene and but-2-ene are functional isomers.

E. Pentane and 2, 2-dimethyl propane are chain isomers.

Choose the correct answer from the options given below:

Options

A.B, C and D only
B.A, B and C only
C.A, B and E only
D.C, D and E only

Solution

are Functional isomer

$${CH}_{3} - CH = CH - {CH}_{3}\ \&\ {CH}_{3} - {CH}_{2} - CH = {CH}_{2} $$Are Positional isomer

$${CH}_{3} - {CH}_{2} - O - {CH}_{2} - {CH}_{3}\ \&{\ CH}_{3} - {CH}_{2} - {CH}_{2} - O - {CH}_{3} $$are Metamer

${CH}_{3} - CH = CH - {CH}_{3}$ does not have optical isomer

Chain isomer
