Draw the structure, name the shape and show bond angles of the molecules XeF4 and SbF4-. In your answer explain why each structure is different, despite both having a central atom, surrounded by 4 fluorine atoms.

Xe is in group 8, the noble gases. Therefore it has 8 electrons in its outer shell. Fluorine atoms have 7 electrons, yet one is an unpaired electron, so this is the electron in fluorine that gets involved in...

By considering the mechanism of the two step reaction of butanone and NaBH4 followed by dilute acid, explain why the product has no effect on plane polarised light.

CH 3 -CO-CH 2 -CH 3 + 2[H] --> CH 3 -CHOH-CH 2 -CH 3 NaBH 4 is a reducing agent that effectively produces an H - ion to act as the reducing agent. The H - ion attacks the electrophilic carbon centre (elec...
