Which of the following is not true regarding a primary amine?a)It forms liquid oxamic esterb)It forms N-alkyl benzene sulphonamidec)It forms mustard oild)It is prepared by Gabriel phthalimide synthesisCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Primary Amines

Primary amines are a type of organic compound that contain a nitrogen atom bonded to two hydrogen atoms and one carbon atom. They are classified as primary amines because the nitrogen atom is only bonded to one carbon atom.

Properties and Reactions of Primary Amines

Primary amines have several important properties and can undergo various reactions. Some of these properties and reactions include:

1. Formation of N-Alkyl Benzene Sulphonamide: Primary amines can react with benzene sulfonyl chloride (C6H5SO2Cl) to form N-alkyl benzene sulphonamides. This reaction involves the substitution of the chlorine atom in the sulfonyl chloride with the primary amine group.

2. Formation of Mustard Oil: Primary amines can undergo a reaction with carbon disulfide (CS2) and an alkali to form a salt called dithiocarbamate. This dithiocarbamate salt can then be treated with an alkyl halide to produce a mustard oil.

3. Gabriel Phthalimide Synthesis: Primary amines can be prepared using a method called the Gabriel phthalimide synthesis. In this synthesis, phthalimide is reacted with potassium hydroxide and an alkyl halide to form a phthalimide salt. This salt can then be hydrolyzed with aqueous acid to produce the desired primary amine.

Answer: Option A

The statement that is not true regarding a primary amine is option A, which states that it forms liquid oxamic ester. Oxamic esters are not typically formed by the reaction of primary amines. Oxamic esters are instead formed by the reaction of a carboxylic acid and hydroxylamine.

To summarize, primary amines have various properties and can undergo different reactions. While they can form N-alkyl benzene sulphonamides, mustard oil, and be prepared by Gabriel phthalimide synthesis, they do not form liquid oxamic esters.

Answer

Primary amines don't form mustard oil, do they?
