(a)
Interpretation:
To identify the carbonyl compound having molecular formula C3H6O. To draw the structures of two possible carbonyl compounds.
Concept introduction:
The hydrocarbons which have general formula CnH2nO are come in the catagory of carbonyl compounds. The carbonyl compounds have R2CO and RCHO
These compounds have same molecular formula but different structural formula. Therfore their systematic names are different. For aldehydes the suffix written in the end of parent carbon chain is -al, while for ketone -one. For example, propanal is an aldehyde and propanone is a ketone.
The reaction of an aldehyde with KMnO4 gives a carboxylic acid. The conversion of an aldehyde to a carboxylic acid is an oxidation reaction, so KMnO4 is acting as a oxidizing agent. However, a ketone does not undergo oxidation in the presence of oxidizing agent.
(b)
Interpretation:
To identify the carbonyl compound having molecular formula C3H6O. To decide which of the structure is correct.
(c) To write the name of product obtained after oxidation.
Concept introduction:
The hydrocarbons which have general formula CnH2nO are come in the catagory of carbonyl compounds. The carbonyl compounds have R2CO and RCHO functional groups. So, carbonyl compounds are of two types (1) Aldehydes (RCHO) (2) Ketones (R2CO).
These compounds have same molecular formula but different structural formula. Therfore their systematic names are different. For aldehydes the suffix written in the end of parent carbon chain is -al, while for ketone -one. For example, propanal is an aldehyde and propanone is a ketone.
