Identifies the following as a alkanes, alkenes, cycloalkenes, or alkynes.

Short Answer

Expert verified

(a) Alkene

(b) Alkyne

(d) cycloalkene.

Step by step solution

Part(a) Step 1:Given information

We have to find out that the given compound is alkanes, alkenes, cycloalkenes, or alkynes.

Part(a) Step 2:Explanation

The following rules are used to determine the IUPAC name of alkenes: Choose the carbon-carbon double-bond chain that is the longest and most continuous. From the end closest to the double bond, count the carbon atoms.

So, if a compound has two bonds, it is an alkene.

Part(b) Step 1:Given information

We have to find out that the given compound is alkanes, alkenes, cycloalkenes, or alkynes.

Part(b) Step 2:Explanation

The following rules are used to determine the IUPAC name of alkyne: Choose the carbon-carbon triple-bond chain that is the longest and most continuous. From the end closest to the triple bond, count the carbon atoms.

So, if a compound has triple bonds, it is an alkyne.

Part(c) Step 1:Given information

We have to find out that the given compound is alkanes, alkenes, cycloalkenes, or alkynes.

Part(c) Step 2:Explanation

So, if a compound has two bonds, it is an alkene.

Part(d) Step 1:Given information

We have to find out that the given compound is alkanes, alkenes, cycloalkenes, or alkynes.

Part(d) Step 2:Explanation

Alkenes are organic molecules made up of carbons and hydrogens joined by a carbon-carbon double bond. Cycloalkenes are alkenes with three or more carbon atoms linked together by at least one carbon-carbon double bond to create a structural ring (thus the prefix 'cyclo-'), as well as alkenes with three or more carbon atoms linked together by at least one carbon-carbon double bond.
