Question

Which one of the following compounds Is consistent with the following IR spectrum? Mass spectrometry is primarily used to determine: molecular formula of a compound molecular weight of a compound conjugation in a compound A & B A & c Which of the following is true about the number of signals in a ^1H NMR spectrum? it indicates the number of neighboring protons it indicates the electronic environment of neighboring protons it indicates the number of different kinds of protons it indicates the electronic environment of absorbing protons it indicates the number of protons in the signal How many signals would you expect in the ^1H NMR spectrum of CH_3OCH_2CH_3? 1 2 3 4 5

Explanation / Answer

9:Mass spectroscopy is primly used to determine both molecular formulae and molecular weight of a compound. Hence option (D) is correct.

10. The number of signals in 1H NMR spectrum indicates the number of different kind of protons. Hence option (C) is correct.

11. There are 3 different types of protons in CH3OCH2CH3. Hence there are 3 different types of signals in 1H NMR spectrum. Hence option (C) is correct.

8: The figure is not clear to answer Q.8. clear image needed
