2E 19

Postby Dakota Walker 1L » Tue Nov 19, 2019 12:05 am

This Question is:
Predict the shapes and estimate the bond angles of (a) the thiosulfate ion, S2O3-2; (b) (CH3)2Be; (c) BH2- ; (d) SnCl2.

Does anyone know how you would predict the shape of B?? (CH3)2Be has so many connections should we only predict the shape of the middle atom? Would this be linear? Can someone please help explain how to approach this problem.

You basically predict the shape around each central atom, so in the case of b, the shape is tetrahedral around the carbon atoms, and the bond angle around the beryllium is 180. You still use all the same rules as if this molecule had only one central atom.
