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