  • What is a functional group in chemistry?
    A functional group is a recognizable part of a molecule responsible for its reactivity and properties.
  • What elements make up hydrocarbons?
    Hydrocarbons are composed solely of carbon and hydrogen atoms.
  • How are alkanes characterized in terms of bonding?
    Alkanes have only single bonds between carbon atoms, with each carbon also bonded to hydrogens.
  • What type of bond is present in alkenes?
    Alkenes contain at least one carbon-carbon double bond.
  • What distinguishes an alkyne from other hydrocarbons?
    Alkynes have at least one carbon-carbon triple bond.
  • What is another name for a benzene ring?
    A benzene ring is also called an aromatic ring.
  • What is a carbonyl group?
    A carbonyl group consists of a carbon atom double bonded to an oxygen atom (C=O).
  • Which functional group is represented by a carbon single bonded to an OH group?
    A carbon single bonded to an OH group is an alcohol.
  • How is an ether functional group structured?
    An ether has two single-bonded carbons connected to the same oxygen atom (C-O-C).
  • What is the defining feature of an amine?
    An amine contains a nitrogen atom single bonded to one or more hydrogens.
  • What does the 'X' represent in an alkyl halide functional group?
    'X' stands for any halogen: fluorine, chlorine, bromine, or iodine.
  • Which functional group contains a carbon single bonded to an SH group?
    A carbon single bonded to an SH group is a thiol.
  • What functional group is characterized by a carbonyl group bonded to an OH group?
    A carbonyl group bonded to an OH group forms a carboxylic acid.
  • How is an ester functional group identified?
    An ester has a carbonyl group bonded to an oxygen, which is then bonded to another carbon (C=O-O-C).
  • What is the difference between an aldehyde and a ketone?
    An aldehyde has a carbonyl group bonded to a hydrogen, while a ketone has a carbonyl group bonded to two carbons.
