Give the coordination number for each metal ion in the following compounds:
(a) [co(co3)3]3− (note that co32− is bidentate in this complex)(b) [cu(nh3)4]2+
(c) [co(nh3)4br2]2(so4)3
(d) [pt(nh3)4][ptcl4]
(e) [cr(en)3](no3)3
(f) [pd(nh3)2br2] (square planar)
(g) k3[cu(cl)5]
(h) [zn(nh3)2cl2]

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
