What is the Lewis Structure of CS2?

Answer 1

:::S-C≡N: resonance with ::S=C=N::

4 pairs either way

Assuming NCS- (as above):

::S=C=N:: is better because the formal charge of -1 is on the most electronegative atom, N.

Answer 2

' ' ' '

S = C = S

. . . .
C = 4 valence electrons

2 x S = 2X6 = 12 valence electrons

that's 16 valence electrons in all

C is least abundant and most electronegative so it goes in the middle of the structure

S = C = S

(in the structure i used the "=" as a double liaison)

there are two links from C so

16 e- -4x2 e- = 16 - 8 = 8 residual electrons

u start filling the electrons around the S in pairs and to respect the octet rule of 8 valence electrons to make it complete and stable.

the final structure is

** **

S = C = S

** **

the " * " are residual electrons

Answer 4

The Carbon atom shares a double bond with both the Oxygen and Sulfur atoms. The oxygen and sulfur atoms each have 2 unshared pairs of electons. Thus the octet rule is fulfilled. Enjoy!
