Question

Among the following compounds I-IV, which one forms a yellow precipitate on reacting sequentially with (i) NaOH (ii) dil. HNO3 (iii) AgNO3 ? fuEufyf[kr ;kSfxdksa I-IV esa ls dkSu&lk ,d (i) NaOH (ii) dil. HNO3 rFkk (iii) AgNO3 ls bl Øe esa vfHkfØ;k djds ihyk vo{ksi cukrk gS ? Cl H3C Cl CH3 Br CH3 Cl CH2 V

(A) I
(B) III
(C) II
(D) IV

Prashant Kotian · Accepted Answer

Correct answer: D. Only in Cl CH2 , I– can be substituted by OH–, I– combine with Ag+ to form yellow ppt of AgI. While in I, II and III substitution reaction is not possible due to partial double bond character.
