Few organic reactions are given below. Which of the reactions is not named correctly?

Options

A. `CH_(3)COOH+C_(2)H_(5)OH overset(H^(+))to underset("(Esterification)") (CH_(3)COOC_(2)H_(5)+H_(2)O)`
B. `CH_(3)COONa +NaOH to underset("(Decarboxylation)")(CH_(4)+Na_(2)CO_(3))`
C. `CH_(3)COOC_(2)H_(5) overset(NaOH)to underset("(Saponification)") (CH_(3)COONa +C_(2)H_(5)OH)`
D. `CH_(3)CH_(2) OH overset("acidified "K_(2)Cr_(2)O_(7))to underset("(Combustion)")(CH_(3)COOH)`

Explanation

To determine which of the given organic reactions is not named correctly, we will analyze each option step by step.

### Step 1: Analyze Option A - "Asstification"
- **Definition**: The term "asstification" seems to be a mispronunciation or misspelling of "esterification."
- **Reaction**: In esterification, an alcohol (e.g., C2H5OH) reacts with a carboxylic acid (e.g., C2H3COOH) in the presence of an acid catalyst to form an ester and water.
- **Conclusion**: Since "asstification" is not a recognized term in organic chemistry, this option is incorrectly named.

### Step 2: Analyze Option B - "Decarboxylation"
- **Definition**: Decarboxylation is the process of removing a carboxyl group (-COOH) from a compound, releasing carbon dioxide (CO2).
- **Reaction**: If we have a carboxylic acid or its salt reacting with a base (like NaOH), it can lead to the release of CO2.
- **Conclusion**: The term "decarboxylation" is correctly named.

### Step 3: Analyze Option C - "Saponification"
- **Definition**: Saponification is the process of making soap by reacting a fat or oil (which is a triglyceride) with an alkali (like NaOH).
- **Reaction**: This reaction produces glycerol and soap (the salt of fatty acids).
- **Conclusion**: The term "saponification" is correctly named.

### Step 4: Analyze Option D - "Oxidation"
- **Definition**: Oxidation refers to the process where a substance loses electrons, often involving the addition of oxygen or the removal of hydrogen.
- **Reaction**: If an alcohol is oxidized, it can convert to a carbonyl compound (aldehyde or ketone) or a carboxylic acid.
- **Conclusion**: The term "oxidation" is correctly named.

### Final Conclusion
The only incorrectly named reaction among the options is **Option A**, which is referred to as "asstification" instead of "esterification."
