Question 1

The product of the reaction of 5-pentanolactam with aqueous acid and heat is 5-aminopentanoic acid.

Accepted Answer

(because the amine-group will be protonated)

Question 2

Sodium borohydride reduces propanamide to propanamine.

Accepted Answer

Sodium borohydride is not strong enough to reduce amides to amines; it typically reduces aldehydes and ketones.

Question 3

The order of reactivity of the carboxylic acid derivatives with water is,

Accepted Answer

The order of reactivity of carboxylic acid derivatives with water is amide < ester < acid chloride < anhydride < carboxylic acid. This means that carboxylic acids are the most reactive, followed by acid anhydrides, acid chlorides, esters, and amides. Water will readily react with carboxylic acids to form a carboxylate anion and a hydronium ion, whereas it will not react with amides under normal conditions.

Question 8

The product of the reaction of 4-butanolactone with ethanol and acid is butanoic acid and diethylether.

Accepted Answer

The product of the reaction between 4-butanolactone (γ-butyrolactone) with ethanol in the presence of acid is ethyl butyrate and water, not butanoic acid and diethyl ether.

Question 11

The proper mechanism for the reaction of acetyl chloride and water is shown below.

Accepted Answer

The image shows the correct mechanism for the reaction of acetyl chloride and water, which involves the formation of an intermediate species called an acylium ion.

Question 13

The reagents that complete the following reaction are,

Accepted Answer

The answer of The reagents that complete the following reaction...

Question 14

The product of the reaction of propanamide with ethanol is ethyl propanoate.

Accepted Answer

The reaction of propanamide with ethanol, typically in the presence of an acid or base catalyst, leads to N-ethylation, producing N-ethylpropanamide, not ethyl propanoate. Ethyl propanoate would be the product of an esterification reaction between propanoic acid and ethanol.

Question 19

Lithium aluminum hydride reduces 3-oxobutanoic acid to 4-hydroxy-2-butanone.

Accepted Answer

Lithium aluminum hydride (LiAlH4) is a strong reducing agent that would reduce 3-oxobutanoic acid to 3-hydroxybutanal, not 4-hydroxy-2-butanone.
