Consider the molecule below.Determine the hybridization at each of the three labelled atoms.

Question

Quizplus · Accepted Answer

- Atom 1: There are two regions of electron density around atom 1 (the double bond and the lone pair). Therefore, it has a hybridization of sp. 
- Atom 2: There are three regions of electron density around atom 2 (the double bond, the lone pair, and the single bond). Therefore, it has a hybridization of sp2. 
- Atom 3: There are three regions of electron density around atom 3 (the double bond, the lone pair, and the single bond). Therefore, it has a hybridization of sp2.

So the correct answer is B) 1 = sp, 2 = sp2, 3 = sp2.
