Roman numerals are used in naming ionic compounds when the metal cation forms more than one ion. The metals that form more than one ion are the transition metals, although not all of them do this.

Consider the following four structures: What is the relationship of I and II? What is the relationship of I and III? What is the
daser333 [38]

Answer:

The different structures are shown in the attachment.

I and II - structural isomers

I and III - Structural isomers

I and IV - structural isomers

II and III - structural isomers

II and IV - structural isomers

III and IV - stereoisomers

Explanation:

The knowledge of Isomerism is tested here; there are two types of isomerism ; structural and stereoisomerism.

  • Structural Isomers have similar molecular and different double bond positioning, these occurs mostly in ALKENE FAMILY.
  • Stereo-isomers have the same molecular formular and similar patterns but differ in their spatial arrangement. trans and cis are typical examples of stereo-isomers.

From the question; Relationship between I and II is that they are structural isomers since they have the same molecular formula, but different bond atom arrangement and infact they are the same compound.

  • Relationship between I and III is that they are structural isomers with similar molecular formular but differ in the double bond position.
  • Relationship between I and IV is that they are structural isomers with similar molecular formula but different double bond arrangement.
  • Relationship between II and III is that they are structural isomers with similar molecular formular but different double bond position
  • Relationship between II and IV is that they are also structural isomers with the same molecular formular but different double bond position.
  • Relationship between III and IV is that they are stereo-isomers with same molecular formula but different spatial arrangement, hence cis and trans.
