Question

Indicate whether each of the following compounds will undergo an addition or a substitution reaction:

• C4 H62
• C3 H63
• C4H8



(a) C4 H62 will undergo an addition reaction, C3 H63 will undergo a substitution reaction, and C4H8 will undergo an addition reaction.
(b) C4 H62 will undergo a substitution reaction, C3 H63 will undergo an addition reaction, and C4H8 will undergo a substitution reaction.
(c) C4 H62 will undergo an addition reaction, C3 H63 will undergo an addition reaction, and C4H8 will undergo a substitution reaction.
(d) C4 H62 will undergo a substitution reaction, C3 H63 will undergo a substitution reaction, and C4H8 will undergo an addition reaction.

Answer 1

C4H6 will undergo an addition reaction, C3H6 will undergo an addition reaction, and C4H8 will undergo a substitution reaction.

Step-by-step explanation:

In order to determine whether each of the given compounds will undergo an addition or substitution reaction, we need to understand their structures and reactivity.

• C4H6: This compound is an alkene, which means it has a double bond between two carbon atoms. Alkenes are highly reactive and typically undergo addition reactions.
• C3H6: This compound is also an alkene, so it will undergo an addition reaction.
• C4H8: This compound is an alkane, which means it only contains single bonds between carbon atoms. Alkanes are relatively unreactive and typically undergo substitution reactions.

Therefore, the correct answer is (a) C4H6 will undergo an addition reaction, C3H6 will undergo an addition reaction, and C4H8 will undergo a substitution reaction.

Answer 2

C4 H62 will undergo a substitution reaction, C3 H63 will undergo a substitution reaction, and C4H8 will undergo an addition reaction. The correct option is D.

Step-by-step explanation:

The given compounds can be analyzed based on their structure and the type of reactions they are likely to undergo.

1. C4 H62 (but-2-yne): This compound contains a triple bond, making it an alkyne. Alkynes typically undergo substitution reactions due to the presence of a π bond. In this case, a substitution reaction is expected.

2. C3 H63 (propyl radical): The presence of a radical indicates a reactive species that is likely to undergo addition reactions. Radicals are known for their reactivity, and in this case, an addition reaction is anticipated.

3. C4H8 (butene): This compound is an alkene, characterized by a double bond. Alkenes are known for undergoing addition reactions. In this case, an addition reaction is expected due to the presence of the double bond.

Therefore, the final answer is (d) C4 H62 will undergo a substitution reaction, C3 H63 will undergo a substitution reaction, and C4H8 will undergo an addition reaction.

In summary, the type of reaction each compound undergoes is determined by its functional group. Alkynes tend to undergo substitution reactions, radicals typically undergo addition reactions, and alkenes usually undergo addition reactions. This analysis is based on the reactivity patterns observed in organic chemistry. The correct option is D.
