Chapter 2, Problem 7P

(a)

Interpretation Introduction

Interpretation:

The stronger acid among HCl and HBr has to be identified.

Concept introduction:

If a base receives one proton, then the formed species is a conjugate acid whereas an acid lose one proton, then the formed species is a conjugated base.

If an acid lose one proton, then the formed species is a conjugated base.  Weak base forms stronger conjugated acid.

Electronegativity:

The chemical behavior of an atom where it attracts the shared electron pair to itself.  Down the group in the periodic table, electronegativity decreases as the number of energy levels increases.

Electronegativity depends on the acidity of a species.  The species having high electronegativity is a weak acid.

(b)

Interpretation Introduction

Interpretation:

The stronger acid among CH3OH and CH3SH has to be identified.

Concept introduction:

If a base receives one proton, then the formed species is a conjugate acid whereas an acid lose one proton, then the formed species is a conjugated base.

If an acid lose one proton, then the formed species is a conjugated base. Weak base forms stronger conjugated acid.

Electronegativity:

The chemical behavior of an atom where it attracts the shared electron pair to itself. Down the group, electronegativity decreases as the number of energy levels increases.

Electronegativity depends on the acidity of a species.  The species having high electronegativity is a weak acid.

(c)

Interpretation Introduction

Interpretation:

The stronger acid among HF and HCl has to be identified.

Concept introduction:

If a base receives one proton, then the formed species is a conjugate acid whereas an acid lose one proton, then the formed species is a conjugated base.

If an acid lose one proton, then the formed species is a conjugated base. Weak base forms stronger conjugated acid.

Electronegativity:

Electronegativity depends on the acidity of a species.  The species having high electronegativity is a weak acid.

(d)

Interpretation Introduction

Interpretation:

The stronger acid among H2S and H2O has to be identified.

Concept introduction:

If a base receives one proton, then the formed species is a conjugate acid whereas an acid lose one proton, then the formed species is a conjugated base.

If an acid lose one proton, then the formed species is a conjugated base.  Weak base forms stronger conjugated acid.

Electronegativity:

The chemical behavior of an atom where it attracts the shared electron pair to itself. Down the group, electronegativity decreases as the number of energy levels increases.

Electronegativity depends on the acidity of a species.  The species having high electronegativity is a weak acid.

Hi I need help with my practice final, it would be really helpful to offer strategies on how to solve it, dumb it down, and a detailed explanation on how to approach future similar problems like this. The devil is in the details and this would be extremely helpful
In alpha-NbI4, Nb4+ should have the d1 configuration (bond with paired electrons: paramagnetic). Please comment.
