The 'H NMR spectrum of an unknown A with molecular formula CaH100 (in CDCI;) is given below in Figure 1. The integrals and integral values for each signal are shown on the spectrum. 3.0 2.0 2.0 2.0 1.0 a 3.0 2.0 1.0 4.0 0.0 5.0 If the spectrum for unknown compound A is recorded in anhydrous CDCI; then similar chemical shifts are obtained as shown in Figure 1 but two of the signals change significantly in their splitting patterns. Describe the changes you would expect and give a brief reason for the difference in the two spectra.
