Identify the oxidation number of the highlighted carbon atoms in each of the molecules.

a. in molecule a a central carbon atom is bonded to two c h 3 groups and an o atom through a double bond.
b. the central carbon atom is highlighted.
c. in molecule b, a central carbon atom is bonded to two c h 3 groups, an o h group, and an h atom.
d. the central carbon atom is highlighted.

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 ,

A) According to these rules the Oxidation state of carbon is +2

B) According to these rules the Oxidation state of carbon is 0

0

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
