Draw the resonance structures for (SCN)".
Phantasy [73]

Answer : The resonance structure of SCN is shown below.

Explanation :

Resonance structure : It is defined as when more than one Lewis structure can be drawn, the molecule or ion is said to have resonance.

Resonance is the concept where electrons (bonds) are delocalized over three or more atoms which cannot be depicted with one simple Lewis structure.

First we have to draw Lewis-dot structure.

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The given molecule is, SCN

As we know that sulfur has '6' valence electrons, carbon has '6' valence electrons and nitrogen has '5' valence electron.

Therefore, the total number of valence electrons in SCN = 6 + 4 + 5 = 15

According to Lewis-dot structure, there are 7 number of bonding electrons and 8 number of non-bonding electrons.

In SCN, carbon atom is the central atom and sulfur and nitrogen are the neighboring atoms.

The resonance structure of SCN is shown below.
