What is the oxidation state the each aspect in COH2? What is the oxidation state that each element in FeBr3?

What is the oxidation state of each element in COH2? What is the oxidation state the each aspect in FeBr3?

Answer


Oxidation state is the variety of electrons shed or obtained by an element during the chemical combination. The ns of electrons to be denoted through

*
sign, while gain of electrons is denoted v
*
sign. The ns of electrons always increases the oxidation number; the get of electrons decreases the oxidation number. The oxidation state the the aspects depends top top the digital configuration that the elements.


Oxidation number: Is the charge on the atom. Based upon the number of electrons exit or gained, oxidation number to be assigned.

For example:


When one atom profit the electrons it was assigned with an unfavorable sign.

*

When an atom loser its electrons climate it to be assigned with positive sign.

(1)

The provided compound is

*

Oxidation state the the oxygen and also hydrogen room

*
respectively.

Oxidation state the each aspect is together follows:


Part 1

The oxidation state of each aspect is as follows:


The oxidation state the hydrogen is constantly and the oxidation state of oxygen is always.

*
therefore the oxidation state the carbon is calculate in the over method. Therefore, the oxidation state of carbon is zero.


Choose the correct route to calculate the oxidation state.

Correct:

*

Incorrect:

*


(2)

The offered compound is

*

Oxidation variety of bromine is.

Oxidation state of each aspect is together follows:


Part 2

The oxidation state of each element is together follows:

*


The fee of bromine is always

*
. So the oxidation state that Fe is calculate by the above method. Therefore, the oxidation state that Fe is
*
.
