# The Color of Chemistry Name: Date: $\qquad$ ## Pre-Lab Questions: 1. Which of the dyes used in this experiment are considered to be azo dyes? Why does this name apply? 2. Redraw the structure of methyl orange (Fig. 2), and identify the groups in the dye that will bind to ionic and polar sites in the fabric.

Step 1
I apologize, but the image you mentioned (Screenshot 2025 - 05 - 23 152840.jpg) is not actually visible in our conversation.

- Azo dyes typically have the general structure $$Ar-N=N-Ar'$$, where $$Ar$$ and $$Ar'$$ represent aromatic rings
Without seeing the full context of the chemistry pre-lab questions, I cannot provide a complete solution. However, I can help you with a general approach to answering these pre-lab chemistry questions about dyes: For Question 1 (Identifying Azo Dyes): - To determine which dyes are azo dyes, I would need to see the molecular structures For Question 2 (Methyl Orange Structure): - I would need to see the original Figure 2 to redraw the structure accurately - Typically, methyl orange has:

Step 2

Polar/ionic binding groups like sulfonate $$(-SO_{3}^{-})

Final Answer

Aromatic ring structures Would you be willing to upload or retype the full image/text so I can provide a precise, step-by-step solution following the LaTeX formatting guidelines?
