Question

What is the Lewis Dot Structure of (CH3)2SeCl2?

What is the VSEPR Class of the molecule?

Answer 1

`(CH_3)_2SeCl_2` => The dot structure of this compound would violate the octet rule as Selenium has 6 valence electrons supporting 4 bonded substrates and a non-bonded electron pair.

The most likely structure should be `(CH_3)_2SiCl_2` => Dimethydichlorosilane

Explanation:

Using Se in this compound would mean the structure would be based upon a trigonal bipyrimidal parent structure with a see-saw geometry. There's probably not a reference in the literature for such a compound, but I'll stand corrected if it is. The most likely structure is Dimethyldichlorosilane which would be `(CH_3)_2SiCl_2`; or, Dimethydichlorosilane and is based upon a Tetrahedral geometry and a dot structure with 4 covalent bonds to the Silicone.
