Answer:
A) Oxidation state of carbon is +2
B) Oxidation state of carbon is 0
Explanation:
In the first question , the compound is propanone.
While assigning oxidation states ,
- <em>We must see to that , </em><em>the electrons in the bond moves towards the most electronegative atom.</em>
- <em>If they are equally electronegative , </em><em>each of them gets 0 oxidation state respectively.</em>
- <em>And if there is one bond , </em><em>the oxidation state obtained by the electronegative atom is -1 and the other is +1.</em>
- The order of electronegativity is as follows :

- <em>Thus
always gets -1 and
always gets +1 in these two compounds.</em> - <em>The carbon - carbon bond will give 0 oxidation state.</em>
<em>A) According to these rules the Oxidation state of carbon is +2</em>
<em>B) According to these rules the Oxidation state of carbon is 0</em>
