Question

factor determine shape of molecule

Answer 1

Write the Lewis dot structure of the molecule. That gives you the steric number (SN) — the number of bond pairs and lone pairs around the central atom.Use the SN and VSEPR theory to determine the electron pair geometry of the molecule.Use the VSEPR shape to determine the angles between the bonding pairs.

Answer 2

The VSEPR predicted shapes of molecules can be found in a systematic way by using the number of electron pairs to determine the shape of the molecules. To predict the shape of the molecules, first draw out the Lewis structure of the molecule. On the Lewis diagram, identify the central atom
