Options:(select one or more)

Answer:
B, C, D
Solution:

Central & Peripheral Units: The complex contains 4 octahedral cobalt units (1 central and 3 peripheral), making statement (A) incorrect.

Edge-Sharing Structures: Each peripheral unit connects to the central cobalt by sharing a common edge formed by two bridging ligands, which confirms statement (B).

Chirality & Isomerism: Due to the propeller-like arrangement of the three chelate-like rings around the central atom, Hexol displays optical isomerism (statement C).

Bridging Ligands: Since there are 3 peripheral units and each contributes 2 bridging hydroxides, there are a total of 6 bridging ligands (statement D).
