- order the following carbonyl groups in terms of reactivity with nucleophiles (least reactive first) acetaldehyde formaldehyde acetone acetyl chloride acetic acidWould the following reaction form the product as shown? (CH3CH₂)2NH H A) Yes, it is easier to form the diketone enolate due to the very acidic nature of the methylene hydrogens in between the two carbonyl groups. B) Yes, it is easier to form the aldehyde enolate than the diketone enolate due to the very acidic alpha hydrogens of the aldehyde. C) NO, it is difficult to form the diketone enolate by abstracting the methylene hydrogens due to steric hindrance from the two carbonyl groups. D) NO, it is difficult to form the aldehyde enolate since the alpha hydrogens of the aldehyde are not that acidic.Q11
