Suppose you used a needle to poke two holes in a sealed tube of toothpaste. One hole near the cap and one hole is in the middle of the tube. You then squeeze the tube at the base. Compare how the toothpaste will leave each needle hole. Be sure to explain using theory, why this happens.

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.
