which of the following least reactive with water a, ch3cocl b, c6h5conh2 c, ch3conh2 d, c6h5cocl
Acid chloride is most reactive towards hydrolysis with water whereas acid amide is least reactive.
Also among acetamide and benzamide, the reactivity of acetamide towards water is higher than the reactivity of benzamide due to steric factor.
Hence, benzamide is least reactive with water.
Option B is correct.
