1. Draw the C4HBr isomer which gives rise to each spectrum below. (Note: each spectrum (a-c) shows a different isomer!) 8. 8 6 4 8 (ppm) 0 The peak around 4 is a sextet and the peak just upfield of 2 is a quintet. The integration is 1:2:3:3 (downfield => upfield). 7 4 0 8 (ppm) From left to right the peaks are triplet, quintet, sextet, and triplet with integrations of 2:2:2:3. 7 3 8 (ppm) The peak at 2 is a nonet (9 lines), and the integrations are 2:1:6.
