Web2 mrt. 2016 · Let's look at the hydration of alkynes. So we're going to start with a terminal alkyne over here. You can see there's a hydrogen on one side of our alkyne. And on the … WebAlcohols (ROH) can be thought of as derivatives of water in which one of the hydrogen atoms has been replaced by an alkyl group. If both of the hydrogen atoms are replaced by alkyl groups, we get an ether (ROR). These compounds are named by adding the word ether to the names of the alkyl groups.
