Question

Ignore chelate conformations. Which statements are correct?

(i) [Ir(NH₃)₄Br₂]⁺ has two geometrical forms, both achiral.

(ii) Tetrahedral [Be(gly)₂], with unsymmetrical N,O-chelates, has an enantiomeric pair.

(iii) trans-[Rh(en)₂Cl₂]⁺ is chiral.

Ma₄b₂ gives achiral cis and trans forms. Two unsymmetrical tetrahedral chelates give mirror-image arrangements. trans-M(AA)₂a₂ is achiral; its cis form is chiral.
