Which of the following can be hydrolysed ?

Options

A. `TeF_(6)`
B. `NCl_(3)`
C. `SF_(6)`
D. Both 1 & 2

Answer

To determine which of the given compounds can be hydrolyzed, we will analyze each option step by step.

### Step 1: Understand Hydrolysis
Hydrolysis is a chemical reaction in which a compound reacts with water, resulting in the breakdown of that compound. Compounds that can undergo hydrolysis typically contain bonds that are susceptible to cleavage in the presence of water.

### Step 2: Analyze the Given Options
Assuming the options are:
1. TeF6 (Tellurium fluoride complex)
2. Another compound (not specified)
3. Another compound (not specified)
4. Another compound (not specified)

We will focus on TeF6 as mentioned in the video transcript.

### Step 3: Hydrolysis of TeF6
TeF6 (Tellurium hexafluoride) can react with water. The reaction can be represented as follows:

\[ \text{TeF}_6 + 6 \text{H}_2\text{O} \rightarrow \text{H}_6\text{TeO}_6 + 6 \text{HF} \]

In this reaction:
- TeF6 reacts with water to form H6TeO6 (telluric acid) and hydrofluoric acid (HF).
- The reaction shows that TeF6 can indeed be hydrolyzed.

### Step 4: Reason for Hydrolysis
The ability of TeF6 to hydrolyze can be attributed to:
- **Size of Tellurium**: Tellurium is a larger atom compared to other elements in group 16 (like oxygen and sulfur).
- **Electronegativity**: Tellurium has a lower electronegativity than these elements, leading to a more polar bond between Te and F. This increased bond polarity makes the bond more reactive and susceptible to hydrolysis.

### Conclusion
Based on the analysis, TeF6 is the compound that can be hydrolyzed.

### Final Answer
The correct option that can be hydrolyzed is **TeF6**.
