Naming Alkanes With Alkyl Groups Quiz
Can you pass this quiz about naming alkanes with alkyl groups? Hydrogen and carbon can combine to form different compounds, and they are grouped into other alkyl groups. Do you think you know enough of these compounds, their chemical formulas and names too? This quiz will help you test out just how much you know about them all. Do check it out and see what new facts you may lean.
Naming Alkanes with Alkyl Groups Questions and Answers
- 1.
A molecule with more than one carbon chain is named after the
- A.
Longest carbon chain
- B.
Shortest carbon chain
- C.
Carbons with the greatest dipole or multipole moment
- D.
Carbons with the lowest dipole or multipole moment
Correct Answer
A. Longest carbon chainExplanation
When naming a molecule with more than one carbon chain, it is named after the longest carbon chain present in the molecule. This is because the main chain determines the base name of the molecule. The other carbon chains, if present, are considered as substituents and are indicated by prefixes in the name. Therefore, the longest carbon chain is the most important factor in determining the name of the molecule.Rate this question:

Name this molecule:
Correct Answer
4-methylnonaneExplanation
The given molecule is named 4-methylnonane. This name indicates that the molecule is a hydrocarbon with a chain of nine carbon atoms (nonane) and a methyl group attached to the fourth carbon atom. The prefix "4-" indicates the position of the methyl group on the carbon chain.Rate this question:

Name this molecule:
Correct Answer
2-methylbutaneExplanation
The molecule is named 2-methylbutane because it consists of a butane chain with a methyl group attached to the second carbon atom. The prefix "2-methyl" indicates the position of the methyl group on the butane chain, which is at the second carbon atom. Therefore, the correct name for this molecule is 2-methylbutane.Rate this question:

Name this molecule:
Correct Answer
3-methylpentaneExplanation
The molecule is named 3-methylpentane because it contains a pentane backbone, which consists of five carbon atoms in a straight chain. The "3-methyl" prefix indicates that there is a methyl group attached to the third carbon atom in the chain. This means that there is a single carbon atom branching off from the third carbon atom. Therefore, the correct name for this molecule is 3-methylpentane.Rate this question:
