The original text contains several issues, making it difficult to interpret and correct accurately. Here is an attempt to rewrite and organize the text meaningfully:

---

Question 1: Solve for x

Solve for [tex]x[/tex].

[tex]\[ 3x = 6x - 2 \][/tex]

---

Question 2: Equilibrium Reaction

A compound "C" is oxidized by periodic acid and gives two products according to the following reaction. Write the correct structure of the compound "C". (2.0 points)

[tex]\[ \text{C} + 3 \text{HIO}_4 \rightarrow 2 \text{HCOOH} + 2 \text{OHHC} \][/tex]

Question 3: Identify Compound Pairs

Consider the six compound pairs below. Label them as enantiomers, epimers, diastereomers, constitutional isomers, or none of these. (2.5 points)

- Pair i. A \& B
- Pair ii. A \& C
- Pair iii. B \& C
- Pair iv. A \& D
- Pair v. E \& F

Question 4: Anomeric Carbons

Circle the anomeric carbons in the following molecules. Identify them as [tex]\alpha[/tex] or [tex]\beta[/tex]. Is it a reducing or non-reducing sugar? Why? (1.5 points)
