See AnswerQ: A dilute solution of 1,3-pentanediol does not produce
A dilute solution of 1,3-pentanediol does not produce the characteristic IR signal for a dilute alcohol. Rather, it produces a signal that is characteristic of a concentrated alcohol. Explain.
See AnswerQ: While13C is the main contributor to the (M+1)+•
While13C is the main contributor to the (M+1)+• peak, there are many other elements that can also contribute to the (M+1)+• peak. For example, there are two naturally occurring isotopes of nitrogen. T...
