Question

Lewis electron dot structure based question. Please answer this.​

Answer 1

Explanation:

The first woman elected president of a country was Vigdís Finnbogadóttir of Iceland, who won the 1980 presidential election as well as three others to also become the longest-serving non-hereditary female head of state in history (16 years and 0 days in office).

Answer 2

Answer:

+1, 0, -1

Explanation:

The formula of formal charge, FC=V−N−B/2  

​

where V  the number of valence electrons of the neutral atom in isolation (in its ground state);

N is the number of non-bonding valence electrons on this atom in the molecule,

and B is the total number of electrons shared in bonds with other atoms in the molecule.

The atoms have been numbered as 1, 2, and 3. The formal charge on:

The central O atom marked 1:

=6−2− 1/2  (6)=     +1

The end O atom marked 2:

=  6−4−1/2(4)=      0

The end O atom marked 3:

=6−6− 1/2  (2)=     −1

Hope this helps you!
