(CH3)2Be shape

Postby Andrea- 3J » Thu Nov 08, 2018 6:32 pm

What is the difference between the solution manual saying (CH3)2Be is a tetrahedral while the molecule as a while is linear? Can someone explain this?

The shape is tetrahedral with respect to the carbon atom because C has 4 regions of bonding density around it (3 H-C bonds, 1 Be-C bond). The shape as a whole (ie with respect to the central atom, Be) is linear because Be only has 2 regions of bonding density (2 Be-C bonds).

So in such cases do we consider C as the central atom or Be? Do have to take into account and write both the shapes?
