Mar 9, 2018 at 1:49 | comment | added | user161158 | is this because of the same reason that resonance is not observed in these molecules? | |
Mar 9, 2018 at 0:55 | comment | added | Jan | @user161158 It is correct that orbital overlap and thus resonance is improved if the atom size is similar — which is usually read as ‘all elements are 2nd period’. So the resonance participation of sulphur in thioacetate is less than that of oxygen in acetate. However, you have managed to choose two examples (bromate and chlorate) in which there is no resonance to be observed. All three — as drawn in my answer — display only single bonds. | |
