Concept explainers
Interpretation: The Lewis structures for each molecule is to be written.
Concept Introduction: Expanded octets are those whose central atoms in a Lewis structure have more than eight electrons in their valence shells and it is one of the exceptions to octet rule.
Lewis structure also known as lewis dot structures represents the molecules by the electron dot model. The Lewis structure represents the sharing of two electrons in the
The molecules obey the octet rule in which each atom has eight electrons in the valence shell. In the molecule, the total number of electron groups around the central atom is equal to the sum of lone pairs, single bond, double bond and triple bond around the central atom.

- Lewis structures can be used to understand why some molecules react in certain ways. Write the Lewis structures for the reactants and products in the reactions described below. a. Nitrogen dioxide dimerizes to produce dinitrogen tetroxide. b. Boron trihydride accepts a pair of electrons from ammonia, forming BH3NH3. Give a possible explanation for why these two reactions occur.arrow_forwardHow does the bond energy of HCl(g) differ from the standard enthalpy of formation of HCl(g)?arrow_forward2. Avogadro does not "waste" his time drawing a Lewis structure before determining the shape of PF3. He thinks that the shape of PF3 must be trigonal planar because there are three fluorine atoms bonded to the central phosphorus atom. a. Draw the Lewis structure for PF3. b. Was Avogadro's answer for the shape of a PF3 molecule correct? Explain c. Why is it important to draw the Lewis structure for a molecule before identifying the shape of the molecule?arrow_forward
