Assertion : Linkage isomerism arises in coordination compounds containing ambidentate ligand. Reason : Ambidentate ligand has two ditferent donor atoms.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Linkage isomerism, observed in coordination compounds with ambidentate ligands like thiocyanate and nitrite, results in distinct isomers due to the ligand binding through different atoms, forming coordination isomers. So the option (1) is correct.
