Answer #1
Concepts and reason

Structure of a molecule can be drawn based on valance of the atoms involved in the structure.

An atom form maximum number of bonds in order to get octet configuration.

Consider the atoms present in the structures; connect them to satisfying their valance. Place the nonbonding electrons on the atoms in the structure.

Fundamentals

Special orientation of atoms present in a molecule is called molecular structure.

Electrons that do not involved in the bond formation are called as non-bonding electrons. The on bonding electrons are generally represented with dots.

Hydrogen forms only one bond with other atoms. Fluorine can also form a single bond to complete its octet. Fluorine belongs to Group 7A of the periodic table, its valance is 1.

Structure of is as follows:

H:

Hydrogen forms only one bond with other atoms. Oxygen can form two bonds to get octet configuration. Oxygen belongs to Group 6A of the periodic table, its valance is 2.

Complete structure is shown below.

H-0-H

Oxygen can form two bonds to get octet configuration. Oxygen belongs to Group 6A of the periodic table, its valance is 2.

Nitrogen can form three bonds to complete its octet configuration. Nitrogen belongs to Group 5A of the periodic table, its valance is 3.

Complete structure is shown below.
