What is the molecular formula and structure?
Mass Spect: 74
IR:2880-2969, 3200-3602
Proton NMR: 0.90 (triplet, 3H), 1.20 (doublet, 3H), 1.48 (quintet, 2H), 3.58 (broad singlet, 1H), 4.05 (sextet, 1H)
Carbon NMR: 9.6, 23.4, 32.8, 70.4
Homework Answers
The IR stretching around 3200-3600 is broad and suggest an -OH group.
From the splitting rule of (n+1) where n is number of adjacent protons can be very well employed to Know the number of hydrogens on each carbon. That is a quintet means 4 adjacent protons.
13C suggests 4 different types of carbon.
