The nitrite ion, NO2-, is known to be angular. The nitrogen atom is the central atom and the oxygen atoms are equidistant from it. On the basis of these facts, which of the following conclusions may be drawn concerning this ion? Choose the answer that includes all the correct conclusions, and no others. I. It can be represented by resonance formulas. II. The dipoles associated with each nitrogen-oxygen bond are equal in magnitude. III. The dipoles associated with the nitrogen-oxygen bonds are opposite in direction. IV. The nitrogen atom is sp hybridized. V. The nitrite ion makes no contribution to the polarity of compounds in which it is contained.
Consider the bonding in the SiH4 molecule. Which response includes all the following statements that are true, and no false statements? I. SiH4 is a polar molecule. II. The H-Si-H bond angles are 120°. III. The SiH4 molecule is tetrahedral. IV. The hybridization of Si is sp2.
1. Lone pairs of electrons repel each other more strongly than bonding pairs repel each other.
2. Lone pairs of electrons repel each other more strongly than they repel bonding pairs.
3. Lone pairs of electrons are considered a part of the electronic geometry about a central atom.
4. Lone pairs of electrons have no effect on the molecular geometry about an atom.
5. Lone pairs of electrons are not considered a part of the molecular geometry about a central atom.
Which response contains all the characteristics listed that should apply to phosphorus trichloride, PCl3, and no other characteristics? I. trigonal planar II. polar bonds III. sp2 hybridized at P IV. polar molecule V. one unshared pair of electrons on P
