On the basis of the molecular formula, 1H NMR data, and IR data provided, propose a consistent structure. Moleculal Formula: C2H3Cl31H NMR data: δ 3.95 (d, 2H), 5.77 (t, 1H)IR data: 2950 cm–1, and several peaks below 820 cm–1.
Identify below compound from its spectral data. Molecular formula:C3H5ClO2 IR:3500–2500 cm−1, 1714 cm−1 1H NMR data:2.87 (triplet, 2 H), 3.76 (triplet, 2 H), and 11.8 (singlet, 1H) ppm
Compound B has molecular formula C9H10. The IR spectrum is shown below. The 1H-NMR spectrum shows a multiplet at 7.2 ppm integrating to 4H, a triplet at 2.9 ppm integrating to 4H, and a triplet at 2.1 ppm integrating to 2 H. Suggest a structure for B and explain your reasoning
