if an unknown compound has a set of peaks at 1750 and 2000cm^-1 as well as a very intense peak between 1680-1740 cm^-1 as well as a very intense peak between 1680-1740cm^-1 what functional group is likely present

2b2t

explanation:

2b2t

i think that the answer is c

i think it's letter a.

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.
