A structural formula shows how atoms in a compound are arranged. A. What atoms constitute the compound above?

B. What class of macromolecules does the compound belong to?

a) The atoms that constitute the compound above are CARBON,HYDROGEN, OXYGEN

b) This Compound belongs to the Carbohydrate class of macromolecules

Carbohydrates are made of carbon hydrogen oxygen in the ratio of 1:2:1 thats why they are also called hydrated carbons compounds when you count all the carbs oxygens and hydrogen you will get this ratio

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.
