Carbon atom in following is sp2 hybridized?
Correct answer: C. HCOOH
- A. CH3CN
- B. CHΞCH
- C. HCOOH
- D. CH2Cl2
Explanation
In formic acid (HCOOH), the carbon atom is sp2 hybridized. This is because the carbon atom is bonded to three atoms (two hydrogen atoms and one oxygen atom) and one electron pair, forming a trigonal planar geometry. Each bond formed by the carbon atom involves the hybridization of one 2s orbital and two 2p orbitals.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
