Why does NH3 have a higher boiling point than BH3?To answer this question, draw out the Lewis structure for each molecule, and then draw out the VSEPR shape for each molecule. Also, Butane is more viscous (has higher intermolecular forces) than ethane. Why?

Draw the structure of CH4, COH4, COH2, AND CO2H2

Between H2O and H2S, which one will have the higher boiling point?  Explain your choice.  HINT:  Think about the intermolecular forces exhibited by the two substances.  Electronegativity values for H, O, and S are 2.1, 3.5, and 2.5.

you are teaching a class in organic chemistry to grade 12 students. describe to them using your knowledege of intermolecular bonding, why methane is a gas at SATPand oentane is a liquid at SATP

19. SF, 20. BrF: 21. SiO; 22. NH.CIO: (indicate the alectron pair gecmatny and molecular shapa around sacha ion.)

describe the hybridization, bonding and geometry in a molecule of benzene. Explain the stability in terms of two resonance structures.

Using the molecular model kit, make and compare the molecular models for CO₂, H₂O, and SO₂. Even though each molecule has 3 atoms, the molecular geometries (shapes) are very different. Explain why the shapes are different. on. -C Polar or Nonpolar Attractive Force O <

Draw the structural formula for the molecule that fits the following description. A small molecule with formula C₂H5O that contains an oxygen bonded to only one carbon. • Include all valence lone pairs in your answer. •You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one.

Which of the following compounds has the highest boiling point and explain your reasoning:  H2S and H2Te

How many constitutional isomers does C2H4Cl2 have? Draw all the isomers using lewis structures.
