# How do you name hemiacetals?

Nov 23, 2015

There are two acceptable names for hemiacetals.

#### Explanation:

Consider the hemiacetal that is formed from butanal and ethanol:

${\text{CH"_3"CH"_2"CH"_2"CH"("OH")"OCH"_2"CH}}_{3}$

You could name this as an alkoxy alcohol.

The name is then 1-ethoxybutan-1-ol.

Or you could name it using the class name "hemiacetal".

The name is then butanal ethyl hemiacetal.

Both names are acceptable.
