Problem IM7.4.
a) bromide b) oxide c) fluoride d) carbonate e) nitrate f) nitrite
g) sulfide h) sulfate i) sulfite j) persulfate k) carbide l) nitride m) arsenide
n) phosphate o) phosphite p) iodide q) iodate r) periodate
Problem IM8.2.
a) (CH3)2CHCH2CH2CN b) CH3CH2CH(OH)CH3
c) (CH3)2CHCOCH2CH3 d) CH3CH2CONHCH2CH3
Problem 10.2.
a) trigonal bipyramidal
b) This time there could be two different answers.
If the lone pair occupies one of the axial positions, it would be pretty close to three other atoms.
If the lone pairs occupies one of the equatorial positions, it would be pretty close to only two other atoms. The other equatorial atoms are pretty far away.
The rule is that the lone pair goes in the less crowded position, so this molecule would be see-saw shaped.
c) Again, there are two possible geometries. One of them would be trigonal planar, a pretty common geometry.
However, that places the lone pairs in the more crowded positions. Instead, the molecule is going to be tee shaped.
