Explanation / Answer

In answering the questions, the following points must be remembered:

1) A bond is formed by the participation of 2 electrons. Therefore, a single bond has 2 bonding electrons.

2) A double bond is a combination of a sigma and a pie bonds. Each bond is formed by the sharing of 2 electrons. Therefore, a double bond has 4 bonding electrons.

3) An element strives to have a total of 8 electrons (sum of bonding and non-bonding electrons) for stable electronic configuration. This is known as the octet rule (8 electrons in the outer shell).

Refer to the pictures given alongside the table and follow the arguments below:

Atom

Bonding electrons

Non-bonding electrons

Total electrons

4 (see that the O atom forms a double bond; each bond is formed by the participation of 2 electrons)

4 (see that the O atom has two pairs of electrons which are not involved in bonding)

8 (the total number of electrons around O will be the sum of bonding and non-bonding electrons)

4 (same argument as for atom 2 above)

8 (a complete electronic shell must contain 8 electrons in total around the atom)

10 (the N atom forms two double bonds, each formed by the participation of 4 electrons, and a single bond with the O atom, again involving 2 electrons)

0 (the N atom has employed all the available electrons)

4 (the O atoms forms 2 single bonds, each involving 2 electrons)

4 (there are 2 pairs of lone electron pairs that are not shared with another atom)

2 (the F atom forms a single bond with O)

6 (three non-shared electron pairs)

6 (three single bonds, one to F and two with 2 H atoms)

6 (N atom forms three single bonds, two to 2 H atoms and one to B)

4 (O atom forms 2 single bonds)

6 (N atom forms a double bond to B and a single bond to O)

8 (B atom forms a total of 4 bonds, a double bond to one N atom and two single bonds to two other N atoms)

Molecule B violates the octet rule. The N atom, marked 4 has 10 electrons around itself. This is clearly a violation of the octet rule.
