Hydrocarbons and Functional Groups

What is the general formula for hydrocarbons with single bonds?

• CnH2n

• CnH2n+2

• CnH2n-2

• CnHn+2

What is the difference between alkanes and alkenes?

• The presence of double bonds in alkenes

• Alkenes are more reactive than alkanes

• The presence of triple bonds in alkenes

• Alkanes have a higher number of carbon atoms than alkenes

What is the functional group present in carboxylic acids?

• Carboxyl group

• Hydroxyl group

• Alkene group

• Amino group

What is the significance of phosphate groups in biological molecules?

• Phosphate groups are involved in energy transfer and the structure of nucleic acids.

• Phosphate groups are only involved in the structure of carbohydrates

• Phosphate groups are only found in non-biological molecules

• Phosphate groups have no role in energy transfer or signal transduction

What is the general formula for alkenes?

• CnHn
