Which of the following imparts green colour to the burner flame?

Options

A. `B(Ome)_(3)`
B. `Na(Ome)`
C. `Al(OPe)_(3)`
D. `Sn(OH)_(2)`

Explanation

To determine which compound imparts a green color to the burner flame, we need to analyze the options provided and understand the chemistry behind the flame coloration.

### Step-by-Step Solution:

1. **Understanding Flame Colors**: Different metal ions produce different colors when burned. For example, copper compounds produce a green flame, while sodium produces a yellow flame.

2. **Identifying the Compounds**: The question provides four options. We need to identify which of these compounds is known to produce a green flame.
- Option A: Trialkyl borate (e.g., B(OR)3)
- Option B: Sodium methoxide (NaOCH3)
- Option C: Aluminium phosphate (Al(PO4)3)
- Option D: Tin hydroxide (Sn(OH)2)

3. **Analyzing Each Option**:
- **Trialkyl Borate**: This compound is known to produce a green flame when burned. This is due to the presence of boron, which can emit light in the green spectrum.
- **Sodium Methoxide**: Sodium typically produces a bright yellow flame, not green.
- **Aluminium Phosphate**: This compound does not produce a green flame; it usually produces a white flame.
- **Tin Hydroxide**: This compound also does not impart a green color to the flame.

4. **Conclusion**: Based on the analysis, the only compound that imparts a green color to the burner flame is **Trialkyl Borate**.

### Final Answer:
The correct answer is **Trialkyl Borate**.
