Chapter 5, Problem 11QAP

Interpretation Introduction

(a)

Interpretation:

Interpret the name of CaH₂ is calcium hydride or not.

Concept Introduction:

The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.

For example in CuCl₂, Cu having + 2 state and thus the name can be written as copper (ii) chloride.

Hence, charge of element is written as number of charge denoted with roman number.

Interpretation Introduction

(b)

Interpretation:

Interpret the name of PbCl₂ is lead (iv) chloride or not.

Concept Introduction:

The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.

For example in CuCl₂, Cu having + 2 state and thus the name can be written as copper (ii) chloride.

Hence, charge of element is written as number of charge denoted with roman number.

Interpretation Introduction

(c)

Interpretation:

Interpret the name of CrI₃ is chromium (iii) iodide or not.

Concept Introduction:

The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.

For example in CuCl₂, Cu having + 2 state and thus the name can be written as copper (ii) chloride.

Hence, charge of element is written as number of charge denoted with roman number.

Interpretation Introduction

(d)

Interpretation:

Interpret the name of Na₂ S is disodium sulfide or not.

Concept Introduction:

The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.

For example in CuCl₂, Cu having + 2 state and thus the name can be written as copper (ii) chloride.

Hence, charge of element is written as number of charge denoted with roman number.

Interpretation Introduction

(e)

Interpretation:

Interpret the name of CuBr₂ is cupric bromide or not.

Concept Introduction:

The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.

For example in CuCl₂, Cu having + 2 state and thus the name can be written as copper (ii) chloride.

Hence, charge of element is written as number of charge denoted with roman number.
