TestHub · Accepted Answer

(I) (i) The carbon bears four different groups (H, OH, Br, CH₃) : chiral. (ii) CH₂Br₂ bears two identical Br atoms : achiral.

(II) (i) 2-Chlorobutane: C₂ bears H, Cl, CH₃, C₂H₅ : chiral. (ii) 2,2-Dichloropropane bears two identical Cl atoms and two methyls : achiral.

(III) (i) The carbon bears H, F, I, CH₃ : chiral. (ii) CH₃CHF₂ bears two identical F atoms : achiral.

Ans. (B) (I) (i) chiral, (ii) achiral; (II) (i) chiral, (ii) achiral; (III) (i) chiral, (ii) achiral.
