Below are some unusual types of bonding, or unexpected types of structures, that we have encountered in this module. Provide one or two examples of compounds that exhibit each of the following unusual or unexpeced behaviors; be sure to provide examples for each of the possibilities:
A. Partial multiple bonding
B. Unexpected strength in a single bond
C. Electron-deficient bonding (or, 3-centered-2-electron bonding)
D. A main group (s or p-block) metal that forms more than one stable oxidation state.
E. A main group (s or p-block) element that can readily exist in both positive and negative oxidation states.
F. A metal ion that can interact with anions with a significant degree of covalency (electron sharing) rather than simply thorugh ionic (electrostatic) interactions.
A. Partial multiple bonding
answer : CH2O, CH3COOH ,HCOOH
B. Unexpected strength in a single bond
answer : H2, F2 ,Cl2
C. Electron-deficient bonding (or, 3-centered-2-electron bonding)
answer : B2H6 , AlCl3, GaF3
D. A main group (s or p-block) metal that forms more than one stable oxidation state.
answer : Pb , Sn, Bi
E. A main group (s or p-block) element that can readily exist in both positive and negative oxidation states.
answer : Cl, Br ,I , O
F. A metal ion that can interact with anions with a significant degree of covalency (electron sharing) rather than simply thorugh ionic (electrostatic) interactions.
answer : Sn , Bi
