Structure OF some important compounds, Boron, Oxides, Halides, Acids (Orthoboric acid, Metaboric Acid, Tetraboric Acid, Borax || Carbon, Oxides (CO,CO2,C3O2) || Halides (CF4,CCL4,CBR4,CF4) || Acids (H2O3,H2C2O4)

Orthoboric acid (H_(3)BO_(3)) and metaboric acid (HBO_(2)) differ in respect of :

Orthoboric acid bahaves as weak monobasic acid giving H_(3)O^(+) and ….
