Question

tell me please what is isostructural species and how i come to know that any compound is isostructural or not

Answer 1

if nh3 & h2o are isostructural species?

Answer 2

NH3 has pyramidal structure, H2o doesnt. They are not isostructural

Answer 3

and wht about hf & h2o?

Answer 4

thanks!

Answer 5

structures depend on the number of bonds in the molecule

Answer 6

ya, dt i knw! h2o has sp3 hybridisation bt i dnt knw about HF???
if its isostructural to h2o?

Answer 7

HF has sp2....so i guess it has trigonal planar . not sure though

Answer 8

Use Valance Shell Electron pair repulsion Theory.

For exams, some memorization is required.

Answer 9

HF cannot be trigonal planar. HF only has 1 hydrogen and 1 flourine. No matter how to try to arrange it, it will still be linear.

Using VSEPR, since carbon in carbon dioxide has no free valance electrons, the shape is linear.

Using VSEPR, water has a bent V shape.

Answer 10

ya..sry.. told u i wasnt sure.

Answer 11

Water has bent V shape due to Bond pair-bond pair attraction ryt?

Answer 12

not attraction, repulsion. the chemguide link outlines what was taught to me.
