What is the hybridization of carbon in a -COOH group?
Correct answer: A. sp²
- A. sp²
- B. sp³
- C. sp
- D. None of these options is correct
Explanation
There are three kinds of hybridizations that a carbon atom may have in a compound: "sp3", "sp2", and "sp". When a carbon has four regions of electron density around it, it has "sp3" hybridization, when carbon has three regions of electron density around it, it has "sp2" hybridization and when carbon has two regions of electron density around it, it has "sp" hybridization. In -COOH, it can be seen that carbon has three regions of electron density around it, thus it has "sp2 "hybridization. So, option A is correct.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
