Which of the following is correct statement regarding carbonyl compounds:

Explanation

A) Carbonyl carbon contains no lone pair: A carbonyl group consists of a carbon atom double-bonded to an oxygen atom (C=O). Carbon has four valence electrons and forms four bonds in this structure (two bonds to oxygen and two single bonds to other atoms). All of its valence electrons are used in bonding, so it has no lone pairs.B) Carbonyl oxygen contains two lone pair: Oxygen has six valence electrons. In a carbonyl group, the oxygen atom uses two of its valence electrons to form the double bond with carbon. The remaining four valence electrons exist as two lone pairs on the oxygen atom.C) Carbonyl group contains two lone pairs: The carbonyl group (C=O) is made up of the carbon and oxygen atoms. As explained above, the carbon atom has zero lone pairs, while the oxygen atom has two lone pairs. Therefore, the entire carbonyl group contains a total of two lone pairs.Since statements A, B, and C are all correct, the most comprehensive and accurate answer is D) All of these.
