Acetone Properties and Structure

The video explores whether acetone (C3H6O) is a polar or nonpolar molecule. It begins by examining acetone's structure, identifying it as a ketone with a carbon double-bonded to oxygen. The video explains that oxygen's higher electronegativity compared to carbon and hydrogen results in a polar molecule, with electrons spending more time around the oxygen, creating a negative charge. A visual representation shows the molecule's polarity, highlighting the negative area around oxygen and the positive area elsewhere. The dipole moment is discussed, showing it runs through the carbon and out the oxygen, confirming acetone's polarity.
