Correct answer: B. CH3CH2CH2OH
- A. CH3Cl(CH)2OH
- B. CH3CH2CH2OH
- C. (CH3)3COH
- D. (CH3)3CHOH

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
