Homework question

Postby sarahtang4B » Mon Nov 26, 2018 9:33 pm

On homework 2.E.19 how do we draw the structure of (CH3)2Be?
Will we be required to know how to draw the lewis structure to determine shape and bond angles? or will test 3 have easier lewis structures than this to determine shapes.

I believe Be is linear between the carbons and each carbon has 3 hydrogens in a tetrahedral arrangement. The formal charge should work out to be 0. Tetrahedral has a bond angle of 109.5 and linear is 180
