Alkane Nomenclature

Front

What is the structural formula for 3-ethyl-3-methylpentane?

Back

C11H24; it has a pentane backbone with an ethyl and a methyl group attached to the third carbon.

Front

What defines a saturated hydrocarbon?

Back

A saturated hydrocarbon has only carbon-carbon single bonds.

Front

What is the name of the structure with three carbon atoms in a straight chain?

Back

The structure is called propane.

Front

How do branches (substituents) affect the boiling point of hydrocarbons?

Back

More branches lower the boiling point due to reduced intermolecular forces of attraction.

Front

What are constitutional isomers?

Back

Constitutional isomers are compounds that have the same molecular formula but different structural formulas.

Front

What is the general formula for alkanes?

Back

The general formula for alkanes is CnH2n+2.

Front

What is the significance of the longest carbon chain in alkane nomenclature?

Back

The longest carbon chain determines the base name of the alkane.

Front

What is a substituent in organic chemistry?

Back

A substituent is an atom or group of atoms that replaces a hydrogen atom in a hydrocarbon.

Front

What is the IUPAC naming convention for branched alkanes?

Back

Identify the longest chain, name it, and then name and number the substituents.

Front

What is the difference between structural isomers and stereoisomers?

Back

Structural isomers differ in the connectivity of atoms, while stereoisomers have the same connectivity but differ in spatial arrangement.
