a.
b.
c.
Short Answer
Expert verified
The compounds that are soluble in water are a and b.
Step by step solution
01
Part (a) Given Information
The given compound is
02
Part (a) Explanation
The given compound is a ketone.
- Aldehydes and ketones are soluble in water.
- The solubility depends upon the length of an alkyl chain.
- More the length of an alkyl chain, the lesser will be the solubility in water.
- Since butanone is a ketone having three carbon atoms chains. Thus, it is soluble in water as it has a shorter length of the alkyl chain.
03
Part (b) Given Information
The given compound is
04
Part (b) Explanation
The given compound is an aldehyde.
- Aldehydes and ketones aresoluble in water.
- The solubility depends upon the length of an alkyl chain.
- More the length of an alkyl chain, the lesser will be the solubility in water.
- Since acetaldehyde is an aldehyde having two carbon atoms chains. Thus, it is soluble in water as it has a shorter length of the alkyl chain.
05
Part (c) Given information
The given compound is:
06
part (c) Explanation
The given compound is an aldehyde.
- Aldehydes and ketones are soluble in water.
- The solubility depends upon the length of an alkyl chain.
- More the length of an alkyl chain, the lesser will be the solubility in water.
- Since 4-methyl-hexanal is an aldehyde having six carbon atoms chains. Thus, it is not soluble in water due to the long length of the alkyl chain.
