THIOALCOHOLS AND DISULFIDES:
... Alcohols add to the carbonyl group of aldehydes and ketones to form hemiacetals and hemiketals respectively. Hemiacetals contain both an alcohol and ether functional group in the same carbon. The two groups are so close to each other that they modify each other’s properties. So we have neither an or ...
