Question

What is the point group of the following structure of the compound?

0 = X 4. т - ил TI -

Answer 1

- Yer FO for point group determination, first we have to look for principle anis where molecule is notated by 360/n Is rotated by 360/n result result in an identical molecule before and after the sotation. The anis with the highest n is principal anis ( Cn anis) So If this molecule by rotation along xe =0 bond by an angle of 180°, we will 947 identical molecule n - principal ands * F - He-f SDS 360 = 180° - 1 gt means it has (anie of symmetry 180° anis so it to this pain cipal a has - two there is molecular plane ovo which results its parallel point group Czv. A o=se é d re in this molecule there is no anús of symmetry but there is one plane. Po If we u Iru If we see this molecule in this way then there is a plane which bisect se, o, and is and reflect two choosine so point group as this has only plane of symmetry is ç. There is a principal anis where sulfur and Fluorine are exchanged to give identical molecule and there is no plane which blect P, S,s and reflect thoo Fluorine F -P- F a Gxs

EERSEN If P, f if plane plane and so pauses through Pir, f then it two selfies will be reflected this molecule has Cav point will birect so there is aor group
