Question

In the given compound, the number of 2° carbon atom/s is _____.

• A. Three
• B. One
• C. Two
• D. Four

Answer 1

The Correct Option is B

To determine the number of secondary (2°) carbon atoms in the given compound, we need to understand the definition of a 2° carbon atom. A secondary carbon atom is a carbon atom bonded to two other carbon atoms.

Analyzing the structure, we identify the types of carbon atoms:

1. The first and last carbon atoms are primary (1°) as they are bonded only to one other carbon atom.
2. The second and fourth carbon atoms are tertiary (3°) because they are bonded to three other carbon atoms.
3. The middle (third) carbon atom is bonded to two other carbon atoms, making it a secondary (2°) carbon atom.

Therefore, the number of secondary (2°) carbon atoms in the compound is one.

Thus, the correct answer is: One.

Answer 2

To determine the number of secondary (2°) carbon atoms in the given compound, we need to understand the definition of a secondary carbon atom. A secondary carbon atom is bonded to two other carbon atoms.

Let's analyze the given compound structure:

1. Observe the first carbon atom (from the left, \(CH_3\)): It is a primary (1°) carbon since it is attached to only one other carbon atom.
2. The second carbon atom (\(C(CH_3)\)): This carbon is attached to two other carbon atoms, making it a secondary (2°) carbon.
3. Continue to analyze each subsequent carbon till the end of the chain:
4. The third carbon (\(CH\)) and the fourth carbon (\(C(CH_3)\)) are primary and tertiary (3°) respectively, as they do not meet the 2° criteria.

After examining the structure, we can confirm that there is only one secondary carbon atom present in the compound.

Therefore, the correct answer is: One
