Give a short written description for all sections (eg. IR, C-NMR, H-NMR, Mass Spec ,any chemical tests described, MW or elemental analysis). Compile data from sections to propose a chemical structure for the unknown.
Homework Answers
IR show band at 2987 cm-1 is due to aliphatic CH streaching
Mass show peak at 43 is due to isopropyl group
And molecular ion peak at 122 m/z and 124 m/z show the 
presence of bromine atom
Therefore the structure of the compound is 2-bromopropane
