Chapter 8.3, Problem 51SSC

Interpretation Introduction

Interpretation:

The steps of drawing the Lewis structure needs to be explained.

Concept introduction:

Lewis dot structure is also known as Lewis dot formula or electron dot structure. The bond formation between the atoms takes place due to the sharing of valence electrons of bonded atoms while the remaining electrons present in outer shell represented as lone pair of electrons. To draw the Lewis structure, calculate the total number of valence electrons in each atom and draw the structure in such a way that each atom gets its octet configuration.

Answer to Problem 51SSC

• Check the valence electron in each bonded atom.
• Count the total number of valence electrons in the given molecule.
• Draw the Lewis structure between bonded atoms in such a way that each bonded atom will get octet configuration.
• Draw the lone pairs with dot or cross and chemical bonds with lines.

Explanation of Solution

Lewis dot structure is the representation which shows the bonding between atoms present in a molecule. It shows lone pairs and bond pairs that existing on each bonded atom. Thus to draw the Lewis structure:

• Check the valence electron in each bonded atom.
• Count the total number of valence electrons in the given molecule.
• Draw the Lewis structure between bonded atoms in such a way that each bonded atom will get octet configuration.
• Draw the lone pairs with dot or cross and chemical bonds with lines.

Conclusion

Thus, the Lewis structure of a molecule depends on the valence electrons of all bonded atoms.
