Afunctional group
Bskeletal structure
Cstructural isomer
Dcarbonyl group
Answer & Solution
Correct answer: A. functional group
1. Certain parts of an organic molecule are responsible for its characteristic chemical behaviour, regardless of the rest of the chain.
2. The text states: "The C–Cl portion of the chloroethane molecule is an example of a functional group, the part or moiety of a molecule that imparts a specific chemical reactivity."
3. A skeletal structure is a drawing style, a structural isomer is a relationship between two different molecules, and a carbonyl group is specifically a C=O group -- none matches this C-Cl description.
4. So the reactive C-Cl portion here is an example of a functional group.
