Final answer:
In the molecule, CH2=CHCH2Cl, both carbon atoms are sp² hybridized.
Step-by-step explanation:
The molecule CH2=CHCH2Cl contains a carbon atom that is bonded to three other atoms: one carbon atom, one hydrogen atom, and one chlorine atom. To determine the hybridization of the carbon atom, we need to count the number of sigma bonds and lone pairs around it.
In this case, the carbon atom has one sigma bond with the hydrogen atom and one sigma bond with the chlorine atom. There are no lone pairs around the carbon atom. Based on this information, we can determine that the carbon atom is sp² hybridized.
The other carbon atom in the molecule is bonded to three hydrogen atoms. It also has no lone pairs around it. Therefore, we can conclude that this carbon atom is also sp² hybridized.
