Lewis Structures/Shape

[aaronharouni]

How would you draw the Lewis structure for (ch3)2be? And what would its shape around the central atom be?

[Anusha 1H]

Because Be has the lowest electronegativity, it would be the central atom. It forms two bonds, so it will bond to each of the carbons, and each of the carbons will have three hydrogen bonds.
Because of the two bonded pairs, this structure would be linear in respect to the Be.

[Jessica Castro 2H]

In respect to the 2 carbon atoms the shape will be tetrahedral.

When it comes to molecules like this, draw the Lewis structure as instructed before. The molecular geometry, as stated above, would be different around the carbon atoms and with respect to the C-Be-C bond. According to the VSEPR model, just note the areas of electron density about these atoms.
