Explain how signal integration of the ¹H NMR spectra will help identify the two compounds.
i) 1-bromoethane
ii) 1,1,2-tribromoethane

• A. Compound (i) will give a ratio of 1:3, while compound (ii) will give a ratio of 2:1.
• B. Compound (i) will give a ratio of 3:2, while compound (ii) will give a ratio of 1:2.
• C. Compound (i) will give a ratio of 2:3, while compound (ii) will give a ratio of 3:1.
• D. NMR integration cannot be used since the compounds will have the same ratio.

Answer: (B)
