What is the common name of the following compound:
3-ethyl-2,5-dimethoxycyclopentanol
This molecule is a cyclopentane ring, and it has attached one ether group, two methoxy groups, and an alcohol. The alcohol takes priority and must be placed at position 1. Then, the lowest numbers will result if we count clockwise around the ring. The correct name for this molecule will be 3-ethyl-2,5-dimethoxycyclopentanol. (Note that on the ring, it is a given that the alcohol is at the 1- position and...
