Chemistry - STEREO ISOMERISM Question with Solution | TestHub

(A) Optical isomerism → chiral/asymmetric carbon present → 1, 2, 4

(B) Geometrical isomerism → C=C with different groups on both carbons → 1, 2, 3

(C) Decolourisation of Br₂/CCl₄ → occurs with unsaturation (C=C or C≡C) → 3, 4

(D) White ppt with ammoniacal Ag⁺ → terminal alkyne (–C≡C–H) → 4
