Aldehydes and Ketones Preparation and Properties

Aldehydes and Ketones Preparation and Properties

→ Aldehydes and ketones are those hydrocarbons derivatives which contains (>C = O) group. In aldehydes, oxygen atom is attached to primary carbon atoms whereas in ketones it is attached to secondary carbon atom.

Aldehydes and Ketones Preparation and Properties 1

→ In aldehyde, carbonyl carbon is attached to alkyl / arylalkyl/aryl group from one side. In ketone carhonyl carbon is attached to alkyl /arylalkyllaryl group on both

Aldehydes and Ketones Preparation and Properties 2

→ which is known as aldehyde group. It is always present at the end of carbon chain. Ketone have functional group > C = O which is known as ketonic group. It is always present in the middle of the chain.

Aldehydes and Ketones Preparation and Properties

→ If both the groups attached to carbonyl groups are same, then it is known as simple ketones and if both the groups are different, then it is mixed ketones.

Aldehydes and Ketones Preparation and Properties 3

→ The general formula for both aldehyde and ketone is CnH2nO.
