Alkane is solid, liquid or gas … Personalized courses, with or without credits. The answer is E. The higher the amount of atoms in a molecule, the higher the molar mass, therefore, the higher the enthalpy of vaporization will be. 8. d. C5H12. 3.7 million tough questions answered. (b) Identify the shape of the CO2 molecule. Draw the Lewis structure of C3H8. How many double bonds are there? Just as there are different methods of notating propane’s chemical makeup, there are different ways of illustrating the structure of a propane molecule. In a Lewis structure of an organic compound, all of the bonds and atoms are shown explicitly, but the bond angles are often shown as 90?. Its Lewis Structure is: There is no single central atom for the molecule, but there are three carbons. (c) One of the two gases dissolves readily in water to form a solution with a pH below 7. How many lone pairs are there? How many dots should be drawn in the Lewis Dot Structure of P2S2? Propane is C3H8. Home. Get the detailed answer: What is the Lewis dot structure for propane, C3H8?
