A) When a negatively charged aluminium wire is brought in contact with an uncharged iron sphere,
(i) the negative charges flow from the aluminium wire to the iron sphere.
(ii) the negative charges flow from the iron sphere to the aluminium wire.
(iii) the positive charges flow from the aluminium wire to the iron sphere.
(iv) the positive charges flow from the iron spher

the answer is learned

the awnser is group 12

what is the question here. i think you messed up.

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.
