How is this correct. how is this not wrong. Did you get it right. If you did explained please.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

particle   p is an electron and particle q is a neutron

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.
