3) CH2,0 4 C H20-20​

Answer 1

Answer:

ch2n+2o2 this is the formula off carbonyl compound

Answer 2

Disclaimer:

The complete question must be

The General molecular formula of carbonyl compounds are

(1) CH₂O₂ (2) CH₂ₙ₊₂O₂  (3) CₙH₂ₙO  (4)CH₂O₂-O

Answer:

The General molecular formula of carbonyl compounds is CₙH₂ₙO. Hence, the correct option is (3) CₙH₂ₙO.

Explanation:

A carbonyl group is a functional group that contains a carbon atom with double-bonded to an oxygen atom.

These two carbonyl groups are divided into two, Aldehydes and Ketone.

The molecular formula of any Aldehyde, The molecular formula of formaldehyde or methanal is CH₂O.

Similarly, the Molecular formula of any Ketone, The molecular formula of Acetone, or 2-propanone is C₃H₆O.

So, it can be observed from the above examples that carbonyl carbons can be represented as CₙH₂ₙO.

Hence, the formula CₙH₂ₙO represents a general molecular formula of carbonyl compounds.
