No, this is not an ethanol.

Explanation:

Ethanol is the name of a specific compound. It is not the name of a class of compounds.

The longest continuous chain consists of two carbon atoms, and it includes the #"CH"_3# group.

The IUPAC name

The name for a two-carbon alkane is ethane.

It consists of the stem eth- and the class name ending -ane.

#underbrace("eth")_color(red)("stem name")"+"underbrace("ane")_color(red)("class name")#

Your compound is an aldehyde.

Its class name ending is -al.

The IUPAC name is stem + class name ending.

Thus, the correct name is ethanal.

The common names of aldehydes come from the corresponding carboxylic acids.

The name of the two-carbon carboxylic acid is acetic acid.

#underbrace("acet")_color(red)("stem name")"+"underbrace("ic acid")_color(red)("class name")#

The class name ending for an aldehyde is -aldehyde.

Thus, the common name of your compound is acetaldehyde.
