Problem 9.31

Ammonia, $$\mathrm{NH}_{3}$$, reacts with incredibly strong bases to produce the amide ion, $$\mathrm{NH}_{2}^{-}$$. Ammonia can also react with acids to produce the ammonium ion, $$\mathrm{NH}_{4}^{+}$$.

(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?

Step-by-Step Solution:

Step 1 of 5) The structures of (a) primitive cubic, (b) body-centered cubic, and (c) face-centered cubic metals. Each structure can be generated by the combination of a single-atom motif and the appropriate lattice. (d) Corner atoms (one shown in red) are shared among eight neighboring cubic unit cells.Notice in the bottom row of Figure 12.11 that the atoms on the corners and faces of a unit cell do not lie wholly within the unit cell. These corner and face atoms are shared by neighboring unit cells. An atom that sits at the corner of a unit cell is shared among eight unit cells, and only 1>8 of the atom is in one particular unit cell. Because a cube has eight corners, each primitive cubic unit cell contains 11>82 * 8 = 1 atom, as shown in Figure 12.12(a). Similarly, each body-centered cubic unit cell [Figure 12.12(b)] contains two atoms, 11>82 * 8 = 1 from the corners and 1 at the center of the unit cell. Atoms that lie on the face of a unit cell, as they do in a face-centered cubic metal, are shared by two unit cells so that only one-half of the atom belongs to each unit cell. Therefore, a face-centered cubic unit cell [Figure 12.12(c)] contains four atoms, 11>82 * 8 = 1 atom from the corners and 11>22 * 6 = 3 atoms from the faces. Table 12.1 summarizes how the fractional part of each atom that resides within a unit cell depends on the atom’s location within the cell.
