The correct Answer is:
To analyze the assertion and reason provided in the question, we will break down the statements and evaluate their validity step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion:** - The assertion states: "Fullerenes are the only pure form of carbon." - We need to evaluate if this statement is true. - Fullerenes are indeed a form of carbon, but they are not the only pure form. Other allotropes of carbon include diamond and graphite. Thus, the assertion is **false**. 2. **Understanding the Reason:** - The reason states: "It contains twenty, five-membered rings and twelve, six-membered rings." - To evaluate this, we need to consider the structure of fullerenes, particularly C60, which is the most well-known fullerene. - The structure of C60 consists of 12 pentagonal (five-membered) rings and 20 hexagonal (six-membered) rings. Therefore, the statement in the reason is also **false**. 3. **Conclusion:** - Since both the assertion and the reason are false, we conclude that the correct answer is that both the assertion and the reason are false. ### Final Answer: Both the assertion and the reason are false. ---

Intramolecular aldol condensation : The aldol condensation also offer a convenient way to synthesize molecules with five and six membered ring.This can be done by an intramolecular aldol condensation using a dialdehyde, a keto aldehyde or a diketone as the substrate.The major product is formed by the attack of the enolate from the ketone side of the molecule that adds to the aldehyde group.The reason the aldehyde group undergoes addition preferentially may arise from the greater reactivity of aldehyde towards nucleophilic addition.In reaction of this type five membered rings from far more readily than seven membered rings and six membered rings are more favourable than four or eight membered rings when possible. 1-Etylcyclopent-1-ene on reductive ozonolysis followed by aq.
