Explanation:

Acetophenone (Option B)
Acetophenone does not react with NaHSO as it does not have any alpha hydrogen atoms. The presence of alpha hydrogen atoms is crucial for the reaction with NaHSO to occur. Acetophenone has a phenyl group attached to the carbonyl carbon, which does not have any alpha hydrogen atoms. Therefore, it cannot undergo the reaction with NaHSO.

Reactivity with NaHSO
Compounds that have alpha hydrogen atoms, such as Acetaldehyde, Acetone, and CH3CHO, can undergo the reaction with NaHSO. The alpha hydrogen atoms are acidic and can be deprotonated by the base formed in the reaction, leading to the formation of the corresponding carbanion intermediate.

Acetophenone Structure
Acetophenone has a phenyl group attached to the carbonyl carbon, which makes it different from the other compounds in the list. The absence of alpha hydrogen atoms in acetophenone makes it unreactive towards NaHSO.

Conclusion
In conclusion, acetophenone does not react with NaHSO due to the absence of alpha hydrogen atoms. On the other hand, compounds like Acetaldehyde, Acetone, and CH3CHO can undergo the reaction with NaHSO because they contain alpha hydrogen atoms that are essential for the reaction to take place.
