Q.1. CH₃CH₂ NH₂ is soluble in
(a) dilute HCl
(b) CuSO₄ solution
(c) AgNO₃
(d) dil. H₂SO₄

Correct Answer is option (a, b, c and d)
Amines being basic in nature dissolve in dilute HCl and dil. H₂SO₄.  They can also coordinate with Cu²⁺ and Ag⁺ ions to form soluble complexes as they can act as good ligands.

Q.2. Which of the following compound cannot be prepared by Gabriel Phthalimide synthesis?
(a) CH₃ - CH₂- NH₂ 
(b) (CH₃)₃ C-NH₂ 
(c) Ph - NH₂
(d)

Correct Answer is option (b, c and d)
Primary aliphatic amines are prepared by Gabriel Phthalimide synthesis.
cannot be prepared because it is a secondary amine. (CH₃)₃ C-NH₂ and Ph - NH₂ cannot be prepared because 3^o alkyl halides and arylhalides cannot be used in this reaction.

Q.3. Aspirin and oil of wintergreen can be distinguished by
(a) Neutral Fecl₃
(b) Aq. NaOH
(c) Aq. NaHCO₃
(d) Br₂/CCl₄

Correct Answer is option (a and c)

Q.4. The reagent (s) used to convert phenol in to Anisole is/are.
(a) NaOH, CH₃l    
(b) CH₂N₂, BF₃
(c) (CH₃)₂ SO₄, NaOH    
(d) NaHCO₃, CH₃I

Correct Answer is option (a, b and c)

Q.5. Which of the following undergo reaction with alcoholic KOH and chloroform?
(a)
(b)
(c)
(d)

Correct Answer is option (a, b, c and d)
Alcoholic solution produces an electrophile :CCl₂. Hence are likely to show reaction.
