Understanding Carbon Compound Nomenclature

What is the general formula for alkanes?

• CnH(2n+2)

• CnH2n

• C3H(2n-1)

• C2nHn

How do you name a branched alkane?

• Use the molecular formula to determine the name.

• Count the number of carbon atoms only.

• Combine all branches without numbering them.

• Identify the longest chain, number it, name branches, and combine names.

What is the suffix used for alcohols?

• -one

• -ol

• -ane

• -ine

What is the difference between an alkane and an alkene?

• Alkanes have a higher boiling point than alkenes.

• Alkanes contain only carbon; alkenes contain oxygen.

• Alkanes are always gaseous; alkenes are always liquid.

• Alkanes have only single bonds; alkenes have at least one double bond.

What is the IUPAC name for CH3-CH2-CH2-CH3?

• butane

• propane

• pentane

• hexane

How do you identify the longest carbon chain in a compound?

• Identify the carbon atoms with the most branches.

• Look for the highest number of double bonds.

• Count the number of hydrogen atoms in the compound.

• Identify the longest continuous chain of carbon atoms in the molecule.

What is the prefix used for a two-carbon alkane?

• but

• eth

• hex

• prop

What is the IUPAC name for C2H5OH?

• Butanol

• Ethanol

• Methanol

• Propanol

What is the functional group of carboxylic acids?

• -CO

• -COOH

• -CHO

• -OH

How do you name a compound with a double bond?

• Name the compound based on its molecular weight.

• Indicate the position of the single bond instead.

• Use the suffix '-ene' and indicate the position of the double bond.

• Use the suffix '-ane' for all compounds.
