Question

Answer the following questions with only one answer a. Carboxylic acid derivatives cannot be hydrolyzed to produce carboxylic acids b. Lithium aluminum (tri-butoxy)hydride will convert acid chlorides to ketones c. Amides have more resonance stability than esters d. Nitriles are less basic than primary amines e. Grignard reagents contain polar covalent carbon-magnesium bonds f. Anhydrides are more reactive than esters in nucleophilic acyl substitution reactions g. Acid chlorides undergo nucleophilic acyl substitution reactions h. Nitriles have an sp hybridized Nitrogen atom i. Esters are more reactive than amides in nucleophilic acyl substitution reactions j. Nucleophilic acyl substitution reactions proceed through a tetrahedral intermediate

Answer 1

a. True

b. True

c. False. It is due to the resonance of oxygen atom involves more energy compare to the resonance of Nitrogen atm.

d. True Due to lone psir electrons of Nitrogen atom involves resonance stabilization.

e. True because carbon more electronegative compare to magnesium atom hence the bond between C and Mg is polar covalent bond.

f. True

g. True

h. True because there are one sigma bond and one lone pair of electron around the Nitrogen atom.

i. Fasle because esters are more stable compare to amides.

j. True
