Q. 6.127 - An Introduction to General, Organic, and Biological Chemistry

Question

Draw the Lewis structure for each of the following:

a. ${\mathrm{Cl}}_2\mathrm{O}$

b. ${\mathrm{H}}_2\mathrm{NOH}$($\mathrm{N}$ is the central atom)

c. ${\mathrm{H}}_2{\mathrm{CCCl}}_2$

Step-by-Step Solution

Answer

(a) The Lewis structure of ${\mathrm{Cl}}_2\mathrm{O}$ is

(b) The Lewis structure of ${\mathrm{H}}_2\mathrm{NOH}$ is

 

(c) The Lewis structure of ${\mathrm{H}}_2{\mathrm{CCCl}}_2$ is

Part (a) Step 1: Given Information

We need to find the Lewis structure of ${\mathrm{Cl}}_2\mathrm{O}$

Part (a) Step 2: Explanation

We know that, 

$\mathrm{Cl}$ belongs to group seven, meaning it possesses seven valence electrons.

$\mathrm{O}$ belongs to group six, meaning it possesses six valence electrons.

As a result, the molecule has a total of $20$ valence electrons.

$\mathrm{O}$ is the center atom because there is only one $\mathrm{O}$ in the molecule.

As a result, the molecule's Lewis structure is:

Part (b) Step 1: Given Information

We need to find the Lewis structure of ${\mathrm{H}}_2\mathrm{NOH}$

Part (b) Step 2: Explanation

We know that, 

$\mathrm{H}$ belongs to group one, meaning it possesses one valence electrons.

$\mathrm{O}$ belongs to group six, meaning it possesses six valence electrons.

$\mathrm{N}$ belongs to group five, meaning it possesses five valence electrons. 

As a result, the molecule has a total of $14$ valence electrons.

$\mathrm{N}$ is the center atom

As a result, the molecule's Lewis structure is:

Part (c) Step 1: Given Information

We need to find the Lewis structure of ${\mathrm{H}}_2{\mathrm{CCCl}}_2$

Part (c) Step 2: Explanation

We know that, 

$\mathrm{H}$ belongs to group one, meaning it possesses one valence electrons.

$\mathrm{Cl}$ belongs to group seven, meaning it possesses seven valence electrons.

$\mathrm{C}$ belongs to group four, meaning it possesses four valence electrons.

As a result, the molecule has a total of $28$ valence electrons.

$\mathrm{C}$ is the center atom

As a result, the molecule's Lewis structure is:
