One of your students asks “Why is water, H2O, a bent molecule (in other words, why is water’s molecular shape bent with an angle of ~105o)? Why isn’t water a linear molecule?” Answer the student’s question clearly, completely, and in detail – starting from the electronic structure of H and O atoms. A Periodic Table and a Table of Electronegativity values are given above.arrow_forward

- Decide whether the Lewis structure proposed for each molecule is reasonable or not. Note: If two or more atoms have the wrong number of valence electrons around them, just enter the chemical symbol for the atom as many times as necessary. For example, if two oxygen atoms have the wrong number of electrons around them, enter the symbol O twice.arrow_forwardAdd lone pairs where needed to give octets and then determine the shape around each indicated atom.arrow_forwardConsider the following ion: BrO3¯. a) Show the full electron configuration for Br. b) Draw the most correct Lewis structure for BrO3¯ and briefly explain why your Lewis structure is correct. c) If the structure is stabilised by resonance, draw at least one of the possible resonance forms.
