On your paper draw the Lewis structure for CO12 and answer ALL the following questions: 1) Are there single bonds, multiple bonds, OR both? 2) Which atom is
the central atom? 3) How many electron groups are present on the central atom?
4) How many lone pair groups are present on the central atom? 5) What is the
name of the molecular shape?

h

the awnser is group 12

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.
