What is an amine?
Back
An amine is a functional group derived from ammonia (NH3) by replacing one or more hydrogen atoms with alkyl or aryl groups. Amines can be classified as primary, secondary, or tertiary based on the number of carbon-containing groups attached to the nitrogen.

FLASHCARD QUESTION
Front
What is an ether?
Back
An ether is a class of organic compounds that contain an oxygen atom connected to two alkyl or aryl groups. The general structure is R-O-R', where R and R' are hydrocarbon chains.

FLASHCARD QUESTION
Front
What is a phosphate group?
Back
A phosphate group is a functional group consisting of a phosphorus atom bonded to four oxygen atoms, one of which is double-bonded. It plays a crucial role in energy transfer (ATP) and is a key component of nucleic acids.

FLASHCARD QUESTION
Front
What is an alkene?
Back
An alkene is a hydrocarbon that contains at least one carbon-carbon double bond (C=C). They are unsaturated compounds and can undergo reactions such as hydrogenation and polymerization.

What is a carbonyl group?
Back
A carbonyl group is a functional group characterized by a carbon atom double-bonded to an oxygen atom (C=O). It is found in various organic compounds, including aldehydes and ketones.

FLASHCARD QUESTION
Front
What are the properties of amines?
Back
Amines are typically basic due to the lone pair of electrons on the nitrogen atom. They can form hydrogen bonds, which gives them higher boiling points compared to hydrocarbons of similar molecular weight.
7.
FLASHCARD QUESTION
Front
How do ethers differ from alcohols?
Back
Ethers have an oxygen atom bonded to two carbon atoms (R-O-R'), while alcohols have a hydroxyl group (-OH) attached to a carbon atom. Ethers are generally less polar and have lower boiling points than alcohols.
