Mechanism Of Nucleophilic Acyl Substitution Of The Acyl Derivative

The mechanism of nucleophilic acyl substitution in the acyl derivative proceedds as follows which among the following is false?

Reaction Mechanism : nucleophilic substitution-sn2

Reaction Mechanism : nucleophilic substitution,1)components OF nucleophilic substitution,nucleophile,Sn1 reactions

Acyl nucleophilic substitution (SNAC) (SNAE)

Arrange the following in the decreasing order of nucleophilic acyl substitution reaction. .

Arrange the following in the decreasing order of nucleophilic acyl substitution reaction. .

Both carbonyl compounds and acid derivatives though they contain grouping yet the reactions given by them are entirely different. As Aldehydes and Ketones give addition product with a nucleophile, while carboxylic acid derivatives give nucleophilic acyl substitution through addition/elimination mechanism. Where X- = -Cl - O-overset(O)overset(||)C-R-OR, -NR(R) etc. Why aldeydes and Ketones give nucleophilic addition reaction while acid derivatives prefer nucleophilic acyl substititution reaction?
