AHow heavy the molecule is
BHow many carbons it has
CHow the molecule was made
DHow the molecule reacts
Answer & Solution
Correct answer: D. How the molecule reacts
1. A functional group is a specific set of atoms together with the bonds between them.
2. That set of atoms is the reactive part of the molecule.
3. The same functional group gives the same reactions whatever the size of the molecule around it.
4. So the functional group is what decides how the molecule reacts.
