1. What is Percentage Yield of Halogen?

Definition: Percentage Yield of Halogen is a measure of the quantity of moles of halogen formed in relation to the reactant consumed in an organic compound.

Purpose: It helps chemists determine the halogen content in organic compounds through silver halide (AgX) formation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( X\% \) — Percentage yield of halogen
• \( At.mass_{halogen} \) — Atomic mass of the halogen (g/mol)
• \( M_X \) — Mass of silver halide (AgX) formed (g)
• \( M \) — Mass of the organic compound used (g)
• 108 — Atomic mass of silver (Ag)

Explanation: The formula calculates the percentage of halogen in the organic compound based on the mass of silver halide formed.

3. Importance of Halogen Yield Calculation

Details: Accurate halogen yield determination is crucial for understanding organic compound composition, purity analysis, and reaction mechanisms.

4. Using the Calculator

Tips: Enter the atomic mass of the halogen (e.g., 35.5 for Cl, 79.9 for Br), mass of AgX formed, and mass of the organic compound. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is silver (Ag) part of the calculation?
A: The method involves converting halogen in the organic compound to silver halide (AgX) for measurement.

Q2: What are typical atomic masses for halogens?
A: Fluorine (19.0), Chlorine (35.5), Bromine (79.9), Iodine (126.9).

Q3: What if my compound contains multiple halogens?
A: This calculator assumes a single halogen type. For mixed halogens, use weighted average atomic mass.

Q4: How accurate is this method?
A: It provides good estimates but may have 1-3% error due to practical limitations in lab measurements.

Q5: Can I use this for fluorine compounds?
A: No, as silver fluoride (AgF) is soluble and doesn't precipitate like other silver halides.
