Assertion:- The carbonyl carbon is a electrophilic and carbonyl oxygen, is a nucleophilic central.
Reason:- carbon oxygen bond is nonpolar in carbonyl compound.

Options

A. If both Assertion `&` Reason are True `&` the Reason is a correct explanation of the Assertion.
B. If both Assertion `&` Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion `&` Reason are False.

Answer

To solve the question, we need to evaluate the assertion and the reason given in the statement.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "the carbonyl carbon is electrophilic and the carbonyl oxygen is a nucleophilic center."
- In carbonyl compounds (C=O), the carbon atom has a partial positive charge due to the electronegativity difference between carbon and oxygen. This makes the carbonyl carbon electrophilic, meaning it can attract nucleophiles.
- The carbonyl oxygen, on the other hand, has a partial negative charge, making it nucleophilic, meaning it can donate electrons.

2. **Evaluating the Reason**:
- The reason states that "the carbon-oxygen bond is nonpolar in carbonyl compounds."
- This statement is incorrect. The carbon-oxygen bond in carbonyl compounds is polar due to the difference in electronegativity between carbon (2.5) and oxygen (3.5). This results in a dipole moment, where the oxygen atom is more electronegative and carries a partial negative charge, while the carbon atom carries a partial positive charge.

3. **Conclusion**:
- The assertion is correct: the carbonyl carbon is electrophilic, and the carbonyl oxygen is nucleophilic.
- The reason is incorrect: the carbon-oxygen bond is polar, not nonpolar.
- Therefore, the assertion is true, but the reason is false.

4. **Final Answer**:
- The correct option is C: Assertion is correct, and Reason is false.
