incorrect answers: trans-4-octene and 1-methylcyclopentene
Homework Answers
The desired compound is not an alcohol as there is no sharp or broad peak above around 3200 cm-1. The compound is not alkene either as there are no signal for C-C double bond stretching in the range 1620 - 1680 cm-1.
The sharp peak at about 1100 cm-1 is due to C-O stretching. So, the desired compound should be dipropyl ether.
