Question

Hybridization of CH3-C=O-CH3

Answer 1

Answer:

sp3 if only single bonds (alkanes, cycloalkanes, alcohols, etc) sp2 if carbon atom has one double bond (alkenes, ketones, etc) sp if carbon atom has one triple bond or two double bonds (alkynes, alkadienes).

Answer 2

sp² and sp³ hybridization

Explanation:

Carbon with all single bonds involve in sp³ hybridization while the carbon with a double bond involve in sp² hybridization.

• The given compound is acetone which is a ketone.
• In this compound two carbon atoms contain all single bonds and one carbon atom that is middle one i.e. carbonyl carbon contain a double bond.
• Thus two carbons which contain all single bonds involve in sp³ hybridization in their first excited state and thus forms four single bonds with three hydrogen's and one carbon atom.
• The carbon atom which contain double bond involve in sp² hybridization in its first excited state and froms three single bonds with two carbon atoms and with an oxygen atom. And it has an unhybridized orbital with an unpaired electron which forms a pi bond with the same oxygen atom.
