The bands that do not appear in product and belong only to reactants are 3100-3000 and 1680-1620.
On addition of Br2 to 2-pentene, the double bond disappears and one bromine each is attached to the double bonded carbons of 2-pentene.
3100-3000 refers to =C-H stretch and it will disappear in product
1680-1620 refers to -C=C- alkene functional group and this too will disappear in product

Question 5 1 pts A student in the organic lab does the reaction seen below. What would be observed in the IR spectra to indicate that the reaction occurred as written below? OH H20+ The student would see a medium band around 3100-3000 in the product that was not in the starting material. The student would see a large, rounded band at 3200-3400 in the product that was not in the starting material. The student would see a large, rounded...
