WebExplanation: sequence of increasing reactivity to HCN addition The reactivity in nucleophilic addition increases with group electrophilicity. Formaldehyde is most reactive towards the addition reaction of hydrogen cyanide to form the corresponding cyanohydrin. The reactivity in nucleophilic addition increases with group electrophilicity greater. WebThe electron density at the carbonyl carbon increases with the increase in the +I effect. As a result, the chances of attack by a nucleophile decrease. Hence, the increasing order of the reactivities of the given carbonyl compounds in nucleophilic addition reactions is: Butanone < Propanone < Propanal < Ethanal Solution 2 paint by numbers peonies https://pauliarchitects.net
