Answer #1

A. Ans : -

Electron-pair geometry for Al in AlBr3 is Trigonal Planar.
There is  Zero lone pair around the central atom, so the geometry of AlBr3is Trigonal Planar.

Explanation :-

Because Central atom i.e. Al do not have any lone pair of electrons, therefore no lone pair - lone pair and lone pair - bond pair repulsions are possible in AlBr3 . Hence geometry ( i.e. Electronic as well as molecular geometry ) of AlBr3 is Trigonal Planar.

B. Ans : -

Electron-pair geometry for Be in BeI2 Linear .
There is  Zero lone pair around the central atom, so the geometry of BeI2 is Linear.

Why is the valence shell electron pair repulsion model used to predict molecular geometry? Lone pair repulsion is stronger than bonding pair repulsion. Valence electrons are constantly moving. Lewis structures of molecules can tell the bond strength between atoms. Lone pair electrons of the central atom are attracted to the bonding pair electrons.
