Before dehydration m/z = 102. After dehydration m/z = 84, difference will 18 due to loss of water molecule
6) ethyl acetate will have band at around 1710 cm-1 is for carbonyl group stretching and strong band at around 1200 cm-1 is for C-O stretching
Whereas 2-butene diol will have strong band at 1600 cm-1 is for C=C stretching and broad band at 3300 cm-1 is for hydroxyl group stretching
7) The mass of the parent compound is m/z 116, after dehydration and alpha cleavage of the carbonyl mass peak is m/z = 83
Add Answer to:
5) What m/z ratio would expect to find in the mass spectrum of the Sollowing compound due to dehydration? 6) Ethyl...

The low‐resolution mass spectrum and m/z data obtained for an
unknown compound seized during
the raid on a clandestine laboratory are provided. Ignore the
signals below m/z 70 and the small
clusters of signals at about m/z 85 and 93. The significant signals
(m/z) and their signal intensities
(%I) from the mass spectrum are: (72,2), (73,5), (74,16),

The mass spectrum of compound A shows molecular ion peak at m/z 88. The IR spectrum of this compound has a broad peak between 3200 and 3550 cm-1. The 1H NMR spectrum of A shows the following peaks: a triplet at d 0.9, a singlet at d 1.1, one more singlet at d 1.15, and a quartet at d 1.6. The area ratio of these peaks is 3:6:1:2. The 13C NMR contains 4 signals. In the space below, propose a...
