NEET Chemistry Question (2024) — Solution
Question
Given below are two statements : Statement I : [ Co ( NH _3 )_6 ]^ 3+ is a homoleptic complex whereas [ Co ( NH _3 )_4 Cl _2 ]^ + is a heteroleptic complex. Statement II : Complex [ Co ( NH _3 )_6 ]^ 3+ has only one kind of ligands but [ Co ( NH _3 )_4 Cl _2 ]^ + has more than one kind of ligands. In the light of the above statements, choose the correct answer from the options given below.
Options
- A. Both Statement I and Statement II are false
- B. Statement I is true but Statement II is false
- C. Statement I is false but Statement II is true
- D. Both Statement I and Statement II are true
Answer
D. Both Statement I and Statement II are true
Step-by-step solution
[ Co ( NH _3 )_6 ]^ 3+ is a homoleptic complex as only one type of ligands ( NH _3 ) is coordinated with Co ^ 3+ ion. While [ Co ( NH _3 )_4 Cl _2 ]^ + is a heteroleptic complex in which Co ^ 3+ ion is ligated with more than one type of ligands, i.e., NH _3 and Cl ^ - .
