Consider the molecular formula of the carbon compounds (a) and (b) given below :
(a) C_{3}H_{3}O
(b) C_{3}H_{6}O_{2}
(i) Identify the functional groups in (a) and (b) and write their structures.
(ii) Are (a) and (b) isomers ? Give reason.
(iii) What happens when alkaline KMnO4 is added, drop by drop, into a test tube containing warm propanol ? Write the chemical equation for the reaction and state the role of alkaline KMnO_{4} in this reaction.

(i) (a) -OH group, alcoholic

  (b) -COOH group, carboxylic group 


(ii)  (a) and (b) are not isomers 


(iii) When alkaline KMnO4 is added, drop by drop, into a test tube containing warm propanol, Propanoic acid is formed

CH3CH2CH2OH ------> CH3CH2COOH

It acts as oxidising agent
