### Interactive Learning Module: Identifying Compounds Using NMR Spectroscopy#### Question 2##### Part aConsider the five compounds shown below. Identify which one matches the provided ^1H NMR spectrum and circle your answer.**Compounds:**- **A:** 2-methylbutane- **B:** 3-methyl-2-pentanone- **C:** 3,3-dimethylbutanoic acid- **D:** 2,2-dimethylpropane- **E:** 3-methyl-2-pentanal**NMR Spectrum:**The provided NMR spectrum has the following characteristics:- **3H** peak around **1 ppm** (triplet)- **6H** peak around **2.5 ppm** (singlet)- **2H** peak around **4 ppm** (doublet)- **1H** peak around **9.5 ppm** (singlet)##### Part bMatch each peak in the NMR spectrum to a specific set of hydrogen atoms in your chosen compound. Use labels such as Ha, Hb, etc., for both your structure and the spectrum.1. **6H** peak (singlet at ~2.5 ppm) - likely corresponds to two equivalent CH3 groups.2. **3H** peak (triplet at ~1 ppm) - likely corresponds to a CH3 group.3. **2H** peak (doublet at ~4 ppm) - likely corresponds to a CH2 group.4. **1H** peak (singlet at ~9.5 ppm) - likely corresponds to an aldehyde proton (CHO).**Note:** Based on these considerations, compound **C** (3,3-dimethylbutanoic acid) is the one that matches the provided ^1H NMR spectrum.##### Part cIdentify which of the compounds (A, B, C, D, E) would exhibit an IR peak at 1710 cm^-1. If none, write "NONE."- **B:** 3-methyl-2-pentanone- **C:** 3,3-dimethylbutanoic acid- **E:** 3-methyl-2-pentanalBoth compounds containing a carbonyl group (C=O) will exhibit an IR peak around 1710 cm^-1, which includes compounds **B**,
