Problem 48P

Assign an oxidation state to each atom in each compound.

(a)  CH4

(b) CH2Cl2

(c) CuCl2

(d) HI

Step-by-Step Solution:

Solution 48P:

Here, we are going to find out the oxidation state of each atom in each of the compound.

Step 1:  (a)  CH4

Hydrogen  belongs to Group (I) element. It has one single valence electron ,that can be easily donate or shared to form bond with C atom.

Thus, in  CH4, Hydrogen has 1+ oxidation state.

Step 2: On the other hand,

Let us consider the oxidation state of Carbon in CH4 i s x

X+ 4 x(1+) =0 X = 4-

Therefore,

Carbon has 4- oxidation state in CH4 molecule

Thus, in CH4, the oxidation state of C is 4- and hydrogen is 1+.

(b) CH2Cl2

Step 3: Hydrogen  belongs to Group (I) element. It has one single valence electron ,that can be easily donate or shared to form bond with C atom.

Thus, in  CH2Cl2 , Hydrogen has 1+ oxidation state.

On the other hand, Cl belongs to Group(VIIA) in the periodic table. It has the highest electronegativity among all the atoms in CH2Cl2.  Therefore, it has a strong tendency to accept one single electron to attain a stable noble gas configuration. Thus, Cl has 1- oxidation state.

Step 4:

Let us consider the oxidation state of Carbon in CH2Cl2 i s x

X+ 2 x(1+)+2(1-) =0 X = 0

Therefore,

Carbon has 0 oxidation state in CH2Cl2 molecule

Thus, in CH2Cl2, the oxidation state of C is 0,  hydrogen is 1+ and Chlorine (Cl) is 1-.

(c) CuCl2
