Give the approximate values for the indicated bond angles in the following molecules: (d)
Ammonia, NH3, reacts with incredibly strong bases to produce the amide ion, NH2-. Ammonia can also react with acids to produce the ammonium ion, NH4+. (a) Which species (amide ion, ammonia, or ammonium ion) has the largest H¬N¬H bond angle? (b) Which species has the smallest H¬N¬H bond angle?
Consider the following XF4 ions: PF4-, BrF4-, ClF4+, and AlF4-. (a) Which of the ions have more than an octet of electrons around the central atom?
Which of the following statements are true?
i. The overall dipole moment of a molecule is the vector sum of its individual bond dipoles.
ii. If atoms A and B in an AB𝑛 molecule have different electronegativities, then the AB𝑛 molecule must have a nonzero dipole moment.
iii. The bond dipoles in a tetrahedral AB4 molecule cancel one another.
a. Does SCl2 have a nonzero dipole moment?
(b) It turns out that ozone, O3, has a small dipole moment. How is this possible, given that all the atoms are the same?
