Question

In Problem 2 tell how many principal signals would probably be observed in the proton NMR spectrum of each compund, and predict the relative areas under the sig- nals An NMR spectrum shows two principal signals with an area ratio of 3:1. Based on this information only, which of the following structures are possibilities? (b) CH2-CHCO2CH (a) CH2 CHCH (c) CH CH CH2CH2CH2CH3 (d) CH CH CH3 (e) CH2-C(CH3)2 (f) CH3CO2CH Calculate the ratios of the different types of hydrogen atoms in a sample when the steps of the integration curve measure 81.5, 28, 55, and 80 mm. A 'H NMR spectrum shows four signals with integration curve heights of 4.0,3.5,5.4, and 5.5 cm. What is the ratio of the types of protons in this sample?
