Question

tag all the sp³ hybridized carbon atoms in this molecule. if there are none, please check the box below. there are none.

Explanation:

Step1: Recall hybridization rules

An $sp^3$ - hybridized carbon has 4 single - bonds.

Step2: Analyze the given molecule

The left - hand carbon atom in the molecule has 4 single bonds (three C - H bonds and one C - C bond). The right - hand carbon has a double bond with oxygen and two single bonds (one C - C and one C - H), so it is $sp^2$ hybridized.

Answer:

The left - hand carbon atom (the one with three H atoms attached) is $sp^3$ hybridized.
