Question 14 Which of the following is or are true? Molecules which have hydrogen bonded to F, 0, or N can undergo hydrogen-bonding London dispersion forces are the result of permanent dipoles in atoms or molecules. Bonding forces are much stronger than intermolecular forces. An intermolecular force is an attractive force that operates between molecules. London dispersion forces occur in all atoms and molecules.

1. For each compound, draw the Lewis dot structure, the number of lone pairs, and the number of electronic groups for the central atom. Each Lewis dot structure follows the octet rule: hydrogen has one bond, all other atoms are surrounded by a total of eight electrons. Each covalent bond counts as we clectrons. Each nonbonded pair of electrons (lone pairs) count as two electrons. The number of nonbonded electrons is how many electrons from the central atom are not...

Which explanation best predicts which species has the smaller bond angle, ClO4− or ClO3−. Which explanation best predicts which species has the smaller bond angle, or . ClO4− will have the smaller bond angle since the chlorine atom must expand its octet to accommodate four oxygen atoms, thus increasing the potential repulsion between each bonding pair of electrons. ClO4− will have the smaller bond angle since it has more electron groups with a total of four electron groups, and more...
