Interpretation: The electron dot structure for given molecules needs to be drawn.
Concept Introduction: An electron dot structure represents the arrangement of total valence electrons in a molecule. Here, electrons are represented as dots in pairs to show the lone pairs as well as the bond pairs.
Explanation of Solution
The molecules in the given example are as follows:
In
The valence electrons of C atom is 4 and that of H atom is 1. Thus, the total number of valence electrons will be:
The arrangement of electrons can be represented as follows:
In
The number of valence electrons of N and Cl atom is 5 and 7 respectively. Thus, the total number of valence electrons will be:
The arrangement of electrons can be represented as follows:
In
Here, S has 2 lone pairs of electrons.
The arrangement of electrons can be represented as follows:
In the HF molecule, 1 H and 1 F atoms are bonded together via a single bond. The valence electrons of the H and F atom is 1 and 7 respectively. Thus, the total number of valence electrons will be 8. Here, F has 3 lone pairs of electrons. The arrangement of electrons can be represented as follows:
