Q8.7(viii):
Which of the following compounds would undergo aldol condensation, which the Cannizzaro reaction and which neither? Write the structures of the expected products of aldol condensation and Cannizzaro reaction.
(viii) Butan-1-ol
Solution :
Step 1: Chemical Structure Analysis
The compound provided is Butan-1-ol. The structural formula is represented as $CH_3-CH_2-CH_2-CH_2-OH$.
Step 2: Identification of Functional Group
The functional group present in Butan-1-ol is a primary alcohol ($-OH$ attached to a terminal carbon).
- Aldol Condensation Requirement: This reaction requires the presence of an $\alpha$-hydrogen atom in an aldehyde or ketone.
- Cannizzaro Reaction Requirement: This reaction requires an aldehyde that lacks $\alpha$-hydrogen atoms.
Step 3: Evaluation of Reactivity
Butan-1-ol is an alcohol, not a carbonyl compound (aldehyde or ketone). Therefore:
- It does not possess the electrophilic carbonyl carbon required for the nucleophilic attack of an enolate (Aldol).
- It does not possess the electrophilic carbonyl carbon required for the hydride transfer mechanism (Cannizzaro).
Step 4: Logical Conclusion
Butan-1-ol contains no carbonyl group. Consequently, it cannot participate in either Aldol condensation or the Cannizzaro reaction.
Final Solution: Butan-1-ol will undergo neither Aldol condensation nor Cannizzaro reaction, as it is an alcohol and lacks the necessary carbonyl functional group.

I am very expert in teaching the basics with simple examples and make to understand the concepts very simple way. It will helpful for the students to understand and apply at a given situation especially application-based and high thinking problems. In fact, I will not teach the student but help to learn the subject in a more independent way and after understanding the level of comfort of the student.

We want to express our deepest gratitude to Sir for his incredible guidance in helping our daughter succeed. He is a highly experienced and knowledgeable educator who truly understands how to connect with students. When our daughter was first introduced to Accountancy in 11th grade, she found the new subject quite challenging and began losing interest. However, thanks to Sir’s consistent support and patience, her performance and confidence improved tremendously. He is deeply sincere, helpful, and always approachable when a student encounters difficulties. Any student would be incredibly fortunate to have him as a mentor, and we highly recommend his tutoring to anyone looking for excellent guidance in Accountancy.

He's one of the most exceptional teacher, I have ever been a student of. Sir teaches in such a way that you can imagine it in your mind, and the concepts never leave you. I was scared of physics earlier, but now I am able to solve questions with much ease and much more confident in it.

I studied physics with Imran Sir in class 11 and 12. He explains the concepts properly with patience. He also taught a lot of tricks to solve questions faster. His classes are fun and i improved a lot over time studying with him.
