Question
**Question:** Choose the frequency of a peak that is most likely to correspond to an sp³ C-H stretch in an IR spectrum. **Options:** - A) 3450 cm⁻¹ - B) 3100 cm⁻¹ - C) 2950 cm⁻¹ - D) 2250 cm⁻¹ - E) 1450 cm⁻¹ **Explanation**: In infrared (IR) spectroscopy, the sp³ C-H stretching vibration usually appears in the range of around 2850 to 2960 cm⁻¹. Therefore, the correct answer is: **C) 2950 cm⁻¹**
