Chapter 9.4, Problem 5PPA

Interpretation Introduction

Interpretation:

The oxidation numbers of each element present in given species are should be given.

Concept introduction:

Rules for assigning the Oxidation number:

• The oxidation number of atom in the elemental form is zero.
• The sum of oxidation numbers of all the atoms present in the molecule is zero.
• The general oxidation number for oxygen is $-2$ and hydrogen is $+1$.
• The combination of any atoms in group 7 the oxidation number is varied.
• The Inter halogen compounds the Fluorine is always having $-1$ oxidation state.
• In the oxohalide compounds oxidation number of halide is in positive.
• The general oxidation state of halides is -1.
• The earth metals always having $+1$ oxidation number only.
• The oxidation state of hydrogen in metal hydride is $-1$.
