Explanation / Answer

28) option C

the carbonyl compounds having 3to 4 carbons per oxygen are soluble in water.

The others have longer alkyl chains(hydrophobic) so not soluble in water.

29)option B

The name is 4-chloro-3-pentylcyclohexanone

31) option C

The ring carbon that is attached to side alkyl chain

the carbon of side chain attached to Cl and ring.

32)option C

Enantiomers are the stereoisomers that are NON-SUPERIMPOSABLE MIRROR IMAGES OF EACH OTHER.

33)option A

they are identical , both are cis
