**Question:**
Choose the frequency of a peak that is most likely to correspond to an O-H stretch in an IR spectrum.

**Options:**

A) 3400 cm⁻¹  
B) 3050 cm⁻¹  
C) 2950 cm⁻¹  
D) 2250 cm⁻¹  
E) 1750 cm⁻¹  

**Explanation:**
In infrared (IR) spectroscopy, the O-H stretch typically appears as a broad peak around 3200-3600 cm⁻¹. Therefore, the correct choice here would be **A) 3400 cm⁻¹** which is within the expected range for an O-H stretch.
