How do you identify an isostructural species?

Hint: To find the isostructural species among the given compounds, we must find the hybridisation of the central atom of each species and the arrangement of the bond pairs and lone pairs on the central atom. To do that, you must recall the VSEPR (Valence shell electron pair repulsion) theory.

What is meant by isostructural species?

Isostructural species are those which have the same shape and hybridisation. Among the given species, identify the isostructural pairs.

What are isostructural species examples?

Hint: Isostructural species: Those species which have the same shape and hybridization, are known as isostructural species. For example: $Xe{F_2}$ and $I{F_2}^ – $ they are isostructural species as they both are $s{p^3}d$ hybridized molecules.

How do you know if two molecules are isostructural?

Two compounds are said to be isostructural, if they have the same structure/geometry. Hence the given compounds are isostructural. As you can see, the HCHO bond angle will be 120 degrees since it has a Trigonal Planar molecular geometry, just like the BH3 molecule.

Which among the following is isostructural?

Complete step by step answer: The Lewis structure of ${I_3}^ – $ is, The iodine atom has two electron domains and two of them are in bonding which means that the geometry is linear and it is ${\text{sp}}$ hybridized. Therefore, the species in option A are isostructural.

Which of the following are isostructural?

Isostructural Compounds having same structure and same hybridisation are known as isostructural species, e.g. XeF2 and IF2 are sp3d hybridised and both have linear shape.

Which one of the following is isostructural?

If a number of bond pairs and lone pairs are same for the given pairs, they are isostructural. If a number of bond pairs and lone pairs are same for the given pairs, they are isostructural.

Which of the following 2 are isostructural?

Explanation: Compounds having same shape with same hybridisation are known as isostructural. XeF2, IF2- + both are sp3d hybridised linear molecules.

What is the geometry of ICl4?

square planar
With five nuclei, the ICl4− ion forms a molecular structure that is square planar, an octahedron with two opposite vertices missing.

Which pairs are isostructural?

NH3 and NH4+

What do you mean by isostructural species?

Isostructural species are those which have the same Shape. Now, one must know what is actually meant by the shape of any molecule. The geometry and shape of a molecule are two different terms. The hybridization of a molecule determine its geometry. For eg.

What are the similarities between isoelectronic and isostructural species?

Isoelectronic chemical species typically display similar chemical properties. Similarly, how do you find isoelectronic and isostructural species? have the same number of electrons around them which are 10 electrons. have same number of electrons and both of them have the same shape which is tetrahedral.

Are CO2 and XeF2 isostructural species?

Although XeF2 have Trigonal bipyramidal geometry unlike CO2 which is linear sp3 hybridised , the shape turns out to be linear which is similar to CO2. Hence, CO2 and XeF2 are isostructural. Therefore, Isostructural species can be identified when their exact shapes are known.

What does isoselectronic mean in chemistry?

Isoelectronic refers to two atoms, ions, or molecules that have the same electronic structure and the same number of valence electrons. The term means “equal electric” or “equal charge”. Isoelectronic chemical species typically display similar chemical properties. Click to see full answer.
