which among the following pairs of compound is not isomorphus
Hello,
Your question is not visible and also incomplete.
Anyway,
I shall tell you about Isomorphism.
In Inorganic Chemistry,when two or more crystals have similar chemical composition exist in the same crystalline form, this property is called isomorphism. For e.g
Sodium nitrate and calcium sulfate.
potassium permanagnet and potassium perchlorate.etc.
I hope this helps.
