Question

1.The bond order of any molecule containing equal numbers of bonding and antibonding electrons is ________.

Select one: A. 2 B. 3 C. 1/2 D. 1 E. 0

2.How many ligands are there in the coordination sphere of [Co(en)2Cl2]+?

Select one: A. 1 B. 3 C. 4 D. 0 E. 6

3.Attack of the nucleophile on the carbon bearing the halogen is the rate-determining step in
nucleophilic substitution of a haloalkane.

Select one:

True

False

4.What is the charge on the complex ion in Ca2[Fe(CN)6]?

Select one: A. 1 B. 2– C. 3– D. 4– E. 2+

5.Coordination sphere isomers ________.

Select one:

A. are the same as resonance structures

B. have different molecular formulae and different coordination numbers

C. have the same molecular formula and coordination number

D. have different molecular formulae but the same coordination number

E. have the same molecular formula but different coordination numbers

1) option E.) 0

bond order = bonding electrons - anti bonding electrons / 2

2) option C.) 4

2 (en) and 2 Cl total 4

3) False

formation of carbo cation is rate - determing step

4) option E ) 2+

Ca2[Fe(CN)6]

2 x (+2) + x + 6(-1) = 0

x = +2

5) option C) have the same molecular formula and coordination number
