Do double bonds count as functional groups?

No  I believe they are just a characteristic that determines between alkanes and alkenes.

I disagree - Double bonds between carbons atoms are funcitonal groups and are prioritised before halogens and alkyl branches when naming molecules :-)

Here's what the textbook said
A functional group is an atom or group of atoms which influences the chemical properties of an organic compound. Would you count a double bond as an atom?

I agree with yoshi97

I think an alkene is still considered a hydrocarbon (like an alkane) and hydrocarbons aren't functional groups...right?

Yeah their not, hydrocarbons consist of functional groups.

Because they are on the list of priorities (when naming) I always thought they were a functional group haha

for the reaction between butane and chlorine, I'd get a chlorobutane. How do I know the states of butane and chlorobutane?

Yeah, it is a functional group. It's called an alkenyl group

And a carbonyl group is definitely a functional group so idk what they're on about
