(1) A, B and E only
Solution
A. CH3CH2CHO (aldehyde) and CH3COCH3 (ketone), both C3H6O functional isomers. Correct.
B. C2H5-O-C2H5 and CH3-O-C3H7, both C4H10O, differ in the alkyl groups on either side of –O– metamers. Correct.
C. But-2-ene has no chiral carbon; it shows geometrical (cis-trans) isomerism, not optical isomerism. Incorrect.
D. But-1-ene and but-2-ene differ only in the position of the double bond position isomers. Incorrect.
E. CH3(CH2)3CH3 and C(CH3)4, both C5H12, differ in the carbon chain chain isomers. Correct.
A, B and E only.
