1. The C-NMR spectrum of triphenylmethanol shows three peaks in
the 120 - 165 ppm range and one peak at 82.3 ppm, however the
unusally tall peak at 127.9 ppm is a very rare case of two
overlapped peaks that are so exactly overlapped they are seen as
one. Draw the structure of triphenylmethanol showing which C's are
equivalent and which are inequivalent and indicate the plane of
symmetry (or rotational exchanges) that exchange equivalent C's in
the molecule. Which...
