What is Organic Chemistry?

Back

Organic Chemistry is the branch of chemistry that deals with the structure, properties, composition, reactions, and preparation of carbon-containing compounds.

Front

Define Hydrocarbon.

Back

A hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.

Front

What are Alkanes?

Back

Alkanes are saturated hydrocarbons with single bonds between carbon atoms, following the general formula CnH2n+2.

Front

What are Alkenes?

Back

Alkenes are unsaturated hydrocarbons that contain at least one carbon-carbon double bond, following the general formula CnH2n.

Front

What are Alkynes?

Back

Alkynes are unsaturated hydrocarbons that contain at least one carbon-carbon triple bond, following the general formula CnH2n-2.

Front

What is Isomerism?

Back

Isomerism is the phenomenon where compounds have the same molecular formula but different structural formulas or arrangements.

Front

Define Functional Group.

Back

A functional group is a specific group of atoms within a molecule that is responsible for the characteristic chemical reactions of that molecule.

Front

What is a Saturated Hydrocarbon?

Back

A saturated hydrocarbon is a hydrocarbon in which all carbon-carbon bonds are single bonds.

Front

What is an Unsaturated Hydrocarbon?

Back

An unsaturated hydrocarbon is a hydrocarbon that contains one or more double or triple bonds between carbon atoms.

Front

Explain the concept of Electrophiles.

Back

Electrophiles are species that accept an electron pair from a nucleophile in a chemical reaction.
