Question

What is the bond angle in dimethyl beryllium?

Answer 1

`/_C-Be-C=180^@`.

Explanation:

WE use VSEPR to predict geometry of main group compounds.

We have `H_3C-Be-CH_3`. Around the central beryllium atom there are 2 regions of electron density, 2 electron pairs which constitute the `C-Be` bonds.

The most stable arrangement is linear. Of course, in a condensed phase, anything could happen. That beryllium compounds are highly poisonous has probably discouraged research.
