In the above picture, suppose the rod was follow instead of solid. Which statement is correct? Due to convection, glob A will melt faster
Due to conduction, glob C will melt first
Due to convection, glob A will take longer to melt
Due to conduction, glob A will melt faster

Due to conduction, glob A will melt faster

Explanation:

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.
