FAQs on Primary,Secondary and Tertiary Carbons Video Lecture - Chemistry for JEE Main & Advanced

1. What are primary, secondary, and tertiary carbons?
Ans. Primary, secondary, and tertiary carbons refer to the classification of carbon atoms based on their connectivity to other carbon atoms. A primary carbon is bonded to only one other carbon atom, a secondary carbon is bonded to two other carbon atoms, and a tertiary carbon is bonded to three other carbon atoms.
2. How do primary, secondary, and tertiary carbons affect the reactivity of organic compounds?
Ans. The reactivity of organic compounds is influenced by the type of carbon atom present. Primary carbons are relatively more reactive compared to secondary and tertiary carbons. This is because the presence of fewer carbon-carbon bonds in primary carbons makes them more susceptible to chemical reactions. On the other hand, tertiary carbons are the least reactive due to the high degree of steric hindrance caused by the three carbon substituents.
3. Can you provide an example of a compound containing primary, secondary, and tertiary carbons?
Ans. One example of a compound containing all three types of carbons is 2-methylbutane. In this compound, the carbon atom at the end of the chain is a primary carbon, the carbon atoms in the middle of the chain are secondary carbons, and the carbon atom attached to the three methyl groups is a tertiary carbon.
4. How does the classification of carbons affect the stability of organic compounds?
Ans. The stability of organic compounds is influenced by the type of carbon atom present. Generally, primary carbons are less stable compared to secondary and tertiary carbons. This is because primary carbons have a higher degree of reactivity and are more prone to undergo chemical reactions. On the other hand, tertiary carbons, with their bulky substituents, provide increased stability due to the steric hindrance that prevents unwanted reactions.
5. Are primary carbons more or less common in organic compounds compared to secondary and tertiary carbons?
Ans. Primary carbons are more common in organic compounds compared to secondary and tertiary carbons. This is because primary carbons are usually present at the ends of carbon chains, which are more abundant in organic molecules. Secondary and tertiary carbons are typically found in the middle or branching points of carbon chains, making them relatively less common.
