Ans: (B) 

Hoffmann bromamide reaction- it is also called degradation reaction as in this reaction primary amide group is treated with halogen first (Br) then the halogen-substituted amide product is converted to a primary amine with the release of carbon dioxide gas.

The students should start the AHSEC HS exam preparation at the begining of the academic session. This is how they can cover the entire Assam HS syllabus at least two months before the exams. This will give the students enough time to understand each topics properly. The students can also practice the Assam Board 12th sample papers and previous years question papers.

Ans: (D)

Lithium aluminium hydride in ether is a strong reducing agent that donates its hydride ion to any C=O containing functional groups into corresponding reduced compounds. Here, the amide group is converted to an amine functional group.

LiAlH₄ in ether is the best reagent for converting 2-phenylpropanamide to 2-phenylpropanamine.

Gabriel synthesis reaction:  

Gabriel’s synthesis is a method for producing primary amines. When phthalimide is treated with ethanolic potassium hydroxide, it forms a potassium salt of phthalimide, which when heated with an alkyl halide and then alkaline hydrolyzed yields the corresponding primary amine. This method cannot produce aromatic primary amines because aryl halides do not undergo nucleophilic substitution with the anion formed by phthalimide.

Ans: (B)

Lithium aluminum hydride in ether is a strong reducing agent that donates its H? hydride ion to any C=O containing a functional group. In addition to LiAlH₄ to aryl nitro compounds, no reaction will be observed, the desired products of amines will not be produced, rather it will form diazobenzene products.

Ans: (C) 

S_N¹ reaction: A nucleophilic reaction that occurs in two steps, first is the bond-breaking step and the second is the production of the carbocation. The stability of carbocation formed in the second step determines the rate of reactivity of reactant toward S_N¹ reaction.  Here, C₆H₅CH₂Br,  

In the process of ionization, removal of bromine, a stable Benzyl carbocation is produced. Therefore, it is best suited for reaction through the S_N¹ mechanism.
