Chemistry: Atoms First V1
- Ethanol, , is a compound in which the formal charge on all the atoms is zero. Under certain conditions the bond can be broken so that both electrons remain with the oxygen atom. The products are In this structure the oxygen owns one electron from shared pair and two electrons from each of unshared pairs. The total number of electrons belonging to oxygen is Oxygen is a Group element. The formal charge on the oxygen atom is . The correct Lewis structure for the ethoxide ion is Note that the other fragment, the proton, leaves with a formal charge of +1.arrow_forwardThe oxygen atom in acetone possesses ____ unshared pairs and ____ shared pairs of electrons. The number of electrons that belong to oxygen is ____. Oxygen is a Group ____ element. The formal charge on oxygen in acetone is ____.arrow_forwardUnshared, or lone, electron pairs play an important role in determining the chemical and phy compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each Be sure your answers are consistent with the formal charges on the formulas. The number of unshared pairs at atom a is The number of unshared pairs at atom b is The number of unshared pairs at atom c is ALI H-A-H bH The number of unshared pairs at atom a is The number of unshared pairs at atom b is The number of unshared pairs at atom c isarrow_forward
