Q. 11.23 - An Introduction to General, Organic, and Biological Chemistry

Question

Identify the following as alkanes, alkenes, cycloalkenes, or alkynes :

Step-by-Step Solution

Answer

a. This compound is $alkene$.

b. This compound is $alkyne$. 

c. This compound is $alkene$ 

d. This compound is $cycloalkene$.

Part (a) Step 1 : Given information.

We have to identify whether the given compound i.e.  is alkane, alkene, alkyne, or cycloalkene.

Part (a) Step 2 : Simplification

We can see that

• The given compound has an unsaturated double bond,
• So it is $alkene$.

Part (b) Step 1 : Given information.

We have to identify whether the given compound i.e.  is alkane, alkene, alkyne, or cycloalkene.

Part (b) Step 2 : Simplification

We can see that

• The given compound has an unsaturated triple bond,
•  So it is $alkyne$.

Part (c) Step 1 : Given information.

We have to identify whether the given compound i.e.  is alkane, alkene, alkyne, or cycloalkene.

Part (c) Step 2 : Simplification

We can see that

• The given compound has an unsaturated double bond, 
• So it is $alkene$.

Part (d) Step 1 : Given information.

We have to identify whether the given compound i.e.  is alkane, alkene, alkyne, or cycloalkene.

Part (d) Step 2 : Simplification

We can see that

• The given compound has an unsaturated double bond in six membered carbon ring, 
• So it is $cycloalkene$.
