The compound which has most acidic hydrogen

Options

A. `CH_(3)CH_(2)NO_(2)`
B.
C.
D.

Answer

To determine which compound has the most acidic hydrogen, we can follow these steps:

### Step 1: Identify the Compounds
We need to look at the given options and identify the compounds that we will analyze for acidic hydrogens.

### Step 2: Identify the Acidic Hydrogen
For each compound, we will identify the hydrogen atom that is most likely to be released as a proton (H⁺). This is typically the hydrogen attached to the most electronegative atom or the one that can stabilize the resulting conjugate base.

### Step 3: Form the Conjugate Base
For the identified acidic hydrogen, we will remove it and form the conjugate base. This involves taking away the H⁺ ion from the compound.

### Step 4: Analyze Stability of the Conjugate Base
We will analyze the stability of the conjugate base formed in the previous step. The stability can often be enhanced by resonance, inductive effects, or the presence of electronegative atoms.

### Step 5: Compare the Stability of Conjugate Bases
We will compare the stability of the conjugate bases of all the options. The more stable the conjugate base, the more acidic the original compound is.

### Step 6: Determine the Most Acidic Hydrogen
Based on the stability of the conjugate bases, we will determine which compound has the most acidic hydrogen.

### Conclusion
After analyzing all the options, we conclude that the compound with the most acidic hydrogen is the one whose conjugate base is the most stable, which in this case is **Option 2**.
