CHAPTER 23 Flashcards
Most organic chemistry involves substituents which are _______________
Groups attached to hydrocarbon chains
The substituents of organic molecules often contain __________________ they are called ____________ because they are the chemicaly functional parts of the molecules
Oxygen, nitrogen, sulfur, phosphorus
Functional groups
What are alkyl halides?
Halocarbons in which a halogen is attached to a carbon of an aliphatic chain
The __________ atoms attached to the alkyl group determines whether the carbon is primary, secondary, or tertiary
Number of carbon
Halocarbons in which a halogen is attached to a carbon of arene ring are called _____________
Aryl halides
The more highly halogenated organic compounds have ___________ boiling points
Higher
Alcohols and alkyl halides are classified as _____________ according to their “degree of substitution”
Primary, secondary, tertiary
Degree of substitution is determined by counting the number of ________ directly attached to the carbon that beats the halogen or hydroxyl group.
