Question

IUPAC name of CH₃CHO is ____________.

Options

• None of these

• Ethanal

• Formaldehyde

• Acetaldehyde

Answer 1

IUPAC name of CH₃CHO is Ethanal.

Explanation:

Because the main chain of CH₃CHO has two carbons, the word root is 'Eth', and a functional group is an aldehydic group, thus the suffix is 'al'. As a result, Ethanal will be the IUPAC name.
