Identify the following as alkanes, alkenes, cycloalkenes, or alkynes:
d. Chemical structure showing a cycloalkene connected to an alkyne with a triple bond between carbon atoms.

Verified step by step guidance
1
Step 1: Understand the definitions of the terms provided in the problem. Alkanes are hydrocarbons with only single bonds between carbon atoms. Alkenes contain at least one double bond between carbon atoms. Cycloalkenes are cyclic hydrocarbons with at least one double bond. Alkynes contain at least one triple bond between carbon atoms.
Step 2: Examine the structure in the image provided. Look for the type of bonds present between the carbon atoms (single, double, or triple) and whether the structure is linear or cyclic.
Step 3: If the structure contains only single bonds, classify it as an alkane. If it contains at least one double bond, classify it as an alkene. If it contains at least one triple bond, classify it as an alkyne. If it is cyclic and contains a double bond, classify it as a cycloalkene.
Step 4: Pay attention to any additional features in the structure, such as the presence of functional groups or branching, but focus primarily on the bonding and cyclic nature to determine the classification.
Step 5: Based on your observations, assign the correct classification (alkane, alkene, cycloalkene, or alkyne) to the structure in the image.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Alkanes

Alkanes are saturated hydrocarbons that contain only single bonds between carbon atoms. They follow the general formula CnH2n+2, where 'n' is the number of carbon atoms. Alkanes are typically less reactive than other types of hydrocarbons and are commonly found in natural gas and petroleum.

Alkenes

Alkenes are unsaturated hydrocarbons characterized by at least one carbon-carbon double bond. Their general formula is CnH2n, indicating that they have fewer hydrogen atoms than alkanes. Alkenes are more reactive than alkanes due to the presence of the double bond, making them important in chemical synthesis and industrial applications.

Cycloalkenes

Cycloalkenes are a subset of alkenes that contain a ring structure and at least one carbon-carbon double bond. They can be represented by the general formula CnH2n-2, reflecting the ring's closure and the presence of the double bond. Cycloalkenes exhibit unique properties and reactivity patterns due to their cyclic structure.
