A student needs to prepare a ¹H NMR sample for an organic compound soluble in chloroform (CHCI3). The student cannot use CHCI 3 as the solvent for the sample, but rather uses deuterated chloroform (CDC13) because: O CDC13 is more polar. O CDC13 will not produce a signal in the ¹H NMR spectrum, and therefore will not mask the signals of the compound. O The compound will be more soluble in CDCI 3. O CDC13 is cheaper than CHCI 3.
