Complete these structures by adding electron dots as needed.

Complete these structures by adding electron dots as needed.

Answer 1

Concepts and reason

The structure of compounds is given and electrons need to be added as dots. Thus, to add the electrons find the atom whose octet is incomplete.

Fundamentals

The valence electrons are represented by dots in the structure. Every atom should contain 8 electrons in valence shell as a sum of bond pair and lone pair except H atom it contains two electrons in its outermost shell. A bond is formed by two electrons. Consider the following example:

In the above example, H is forming a bond by sharing its one electron to complete two electrons in its outermost shell. Similarly, Cl is completing its octet by sharing one electron in forming bond with H and rest of the electrons are represented as lone pair, that is, electron dots in the structure over Cl.

Draw the structure of the given compound and represent the electron dots as shown below:
