1. NEET 2026MediumDiazonium Salts
   Q1

   The major product Z formed in the following sequence of reactions is C₂H₆ →[Cl₂/UV light] (monochlorinated product) X →[NH₃] Y →[(i) NaNO₂] Z

   • AC₂H₅NO₂
   • BC₂H₅N=N-OH
   • CC₂H₅OH
   • DC₂H₅NH₂

   Show answer & solution

   Correct answer: (C)

   Ethane chloination gives chloroethane (X). Reaction with NH₃ gives ethylamine (Y). Diazotisation with NaNO₂ gives ethanol (Z) via diazonium salt.
2. NEET 2025Easy
   Q2

   The correct order of decreasing basic strength of the given amines is:

   • AN -ethylethanamine > ethanamine > N-methylaniline > benzenamine
   • Bbenzenamine > ethanamine >N-methylaniline >N-ethylethanamine
   • CN -methylaniline > benzenamine > ethanamine > N-ethylethanamine
   • DN-ethylethanamine > ethanamine > benzenamine > N-methylaniline

   Show answer & solution

   Correct answer: (A)

   Lower is the value of pKb , higher is the basicity Also aliphatic amines are stronger bases than aromatic amines. pKb :
   
   Benzenamine > N-Methylaniline > Ethanamine > N-EthylethanamineBasic strength : N-Ethylethanamine > Ethanamine > N-Methylaniline > Benzenamine
3. NEET 2024EasyAmines and Preparation Methods
   Q3

   Given below are two statements:
   
   Statement I : Aniline does not undergo Friedel-Crafts alkylation reaction.
   Statement II : Aniline cannot be prepared through Gabriel synthesis.
   In the light of the above statements, choose the correct answer from the options given below:
   [NEET 2024]

   • ABoth statement I and Statement II are true
   • BBoth Statement I and Statement II are false
   • CStatement I is correct but Statement II is false
   • DStatement I is incorrect but Statement II is true

   Show answer & solution

   Correct answer: (A)

   Aniline does not undergo Friedel-Crafts alkylation reaction due to salt formation with aluminium chloride, the Lewis acid, which is used as a catalyst.
   
   Aniline (aromatic primary amine) cannot be prepared by Gabriel phthalimide synthesis because aryl halides do not undergo nucleophilic substitution with anion formed by phthalimide.
