What is a chlorine free radical?

Back

A chlorine free radical is an uncharged species with 17 electrons, formed by the homolytic fission of a chlorine molecule.

Front

What is the electron count of a chlorine free radical?

Back

A chlorine free radical has 17 electrons.

Front

What type of reaction occurs between ethane and chlorine in sunlight?

Back

The reaction is a free radical substitution.

Front

What is the functional group of an aldehyde?

Back

The functional group of an aldehyde is the carbonyl group (C=O) at the end of the carbon chain.

Front

What is the difference between aldehydes and ketones?

Back

Aldehydes have the carbonyl group at the end of the carbon chain, while ketones have it within the chain.

Front

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).

Front

What is free radical substitution?

Back

Free radical substitution is a reaction mechanism where free radicals replace atoms or groups in a molecule.

Front

What is the structure of 2,3,3-trimethylpentane?

Back

2,3,3-trimethylpentane is a branched alkane with a pentane backbone and three methyl groups attached to the second and third carbon.

Front

What is the general formula for alkanes?

Back

The general formula for alkanes is CnH2n+2.

Front

What is the significance of homolytic fission in organic reactions?

Back

Homolytic fission is significant because it generates free radicals, which are key intermediates in many organic reactions.
