Trioxides

Sulphur & its Allotropes, Sulphur Dioxide, Sulphur Trioxide, Sulphoric Acid, Oxoacids OF Sulphur

VA group elements form tri oxides and pentoxides of the type M_(2)O_(3) and M_(2)O_(5) respectively (M-VA group element). The trioxides and pentoxides of nitrogen are monomers and that of P,As,Sb are dimers. Nitrogen forms various oxides ranging from NO to N_(2)O_(5) . Oxides of phosphorous have cage like stuctures. Number of P-O-P bonds in P_(4)O_(10) :
