Question

the chemical structure of 2 - hydroxyethanal (ch₂ohcho) is shown below. highlight each atom that is in a hydroxy group.

Explanation:

A hydroxy group is -OH. In the structure of 2 - hydroxyethanal (\(CH_2OHCHO\)), we look for the -OH part. The oxygen (\(O\)) and hydrogen (\(H\)) atoms in the -OH group are the ones to be highlighted.

Answer:

Highlight the oxygen (\(O\)) and hydrogen (\(H\)) atoms in the -OH group (the \(O - H\) part in the structure).
