Question

write the rules which are applied while the formulae of coordination compound

Answer 1

$\boxed{HIYAAAMATEY!!!}$

(1) Longest Chain rule : we have to select the longest chain of carbon atom which is known as parent chain or principle chain. All the other carbon atoms constitute in the chain are branched chains or side chains..

(2) Lowest number rule : the carbon compound which contains only one substituent number the carbon atom in such a way that the carbon atom carrything the substituent gets the lowest number..

(3) Lowest sum rule : if there are two or more substituents i the carbon compounds the parent chain is numbered from the end which gives the lowest sum of more substituent carbon...

(4) Alphabetical order : when two or more different functional groups are present,, such groups are arranged in alphabetical order..

Answer 2

Explanation:

The formula of such complex compounds are written as per of the following rules: (i) Central atoms is written first. (ii) It is followed by the symbols of the ligands which are written in the order-negative ligands, neutral ligands followed by positive ligands.
