Why C3H6O2 is polar
Ethyl formate has the arrangement H–C(=O)–O–CH2CH3. The two oxygens are concentrated near one end, leaving an uneven charge distribution.
What to notice
Ethyl formate and propionic acid have the same formula C3H6O2 but are different functional-group isomers: ester versus carboxylic acid.
