Differentiate between the aldehyde and ketone ?

( Answer point wise )​

Answer 1

• You will remember that the difference between an aldehyde and a ketone is the presence of a hydrogen atom attached to the carbon-oxygen double bond in the aldehyde.

• Ketones don't have that hydrogen. The presence of that hydrogen atom makes aldehydes very easy to oxidize (i.e., they are strong reducing agents

Answer 2

Answer:

difference between an aldehyde and a ketone is the presence of a hydrogen atom attached to the carbon-oxygen double bond in the aldehyde. Ketones don't have that hydrogen. The presence of that hydrogen atom makes aldehydes very easy to oxidize (i.e., they are strong reducing agents)

• Both aldehydes and ketones contain a double bond between carbon and oxygen.

• Aldehydes have the double bond at the end of the molecule. That means the carbon at the end of the chain has a double bond to an oxygen atom.

• Ketones have the double bond anywhere in the molecule except for the end. That means you will see a double bond to oxygen from one of the carbon atoms in the middle of the chain.

• If you've got a solution and you don't know if it's an aldehyde or a ketone, you can use Tollen's Reagent to help. You can add some of the reagent to your solution and if you see a silver colour, there is aldehyde present. Tollen's Reagent has the formula [Ag(NH3)2]NO3 and it can oxidise aldehydes but not ketones! If you add Tollen's Reagent to a ketone, nothing will happen

I hope it will help you
