Question

Answer

Transcription of this question: Some physical properties of molecular substances result from the different types of forcesbetween their molecules.Explain why the hydrides of group 16 elements (H20, H2S, H2Se and H2Te) arepolar molecules.The graph shows the boiling points of the hydrides of group 16 elements.H2S[2]H202H2Se4H2Te53PeriodExplain the increase in the boiling point from HS to H2Te.[2](b)Lewis structures show electron domains and are used to predict molecular geometry.Deduce the electron domain geometry and the molecular geometry for the NH2- ion.[2]Electron domain geometry:Molecular geometry:
