the orbital diagram below is written incorrectly. why?

a. the number of electrons used is incorrect.

b. the orbitals are not in the correct sequence.

c. the orbital diagram violates hund's rule.

d. the electrons are all paired.

The answer to your question is: letter C

Explanation:

Hund's rule: states that electrons always enter an empty orbital before they pair up.

In this exercise, we notice that orbital p has three suborbitals, then,

we must start filling each suborbitals with one electrons and after that we start to pairing them up.

The result must be,

1st suborbital with 2 electrons

2nd suborbital with 1 electron

3 rd suborbital with 1 electron

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
