1.	The following complexs are given? trans-`[Co(NH_(3))_(4)1_(2)]^(o+)` `cis-[Co(NH_(3))_(2)(en)_(2)]^(3+)` trans-`[Co(NH_(3))_(2)(en)_(2)]^(3+)` `[NiI_(4)]^(2-)` `[TiF_(6)]^(2-)` `[CoF_(6)]^(3-)` Choose the correct code .A. (1),(2) are optically active,B. (2) is optically active, (1), (3) are optically inactiveC. (4),(6) are colourless (5) is colouredD. (4) is coloured and (5) is colourless
Answer» Correct Answer - b,d (1) and (3) are symmetrical not opticaly active. (5) has `Ti^(4+)(d^(0))` configuration.
