Question

For each of the following, draw the Lewis structure, predict the ONO bond angle, and give the hybridization of the nitrogen. You may wish to review the chapters on chemical bonding and advanced theories of covalent bonding for relevant examples.

Answer 1

The Lewis structure of HNO3 is drawn, ONO bond angle is predicted to be 120 degrees, and the hybridization of nitrogen is determined to be sp2.

Step-by-step explanation:

The Lewis structure of HNO3 can be determined by arranging the atoms and their valence electrons. Nitrogen (N) is the central atom, surrounded by three oxygen (O) atoms. Each oxygen atom is connected to the nitrogen atom through a single bond.

The Lewis structure will have a double bond between one oxygen and the nitrogen atom, resulting in the following structure:

O = N - O-

The ONO bond angle in HNO3 is approximately 120 degrees. The hybridization of the nitrogen atom can be determined based on the number of regions of electron density it has, which is 4 in this case. With 4 regions of electron density, the nitrogen atom in HNO3 undergoes sp2 hybridization, resulting in three sp2 hybridized orbitals.
