Match the pairs from column A and B Column A Column B A BCl 3 p Angular molecule B SiO 2 q Linear covalent molecule C CO 2 r Tetrahedral molecule s Planar trigonal molecule

BCl 3 is a trigonal planar molecule like the other boron trihalides. In the Lewis structure for the central atom (Boron) will only have six valence electrons, each bond representing two electrons. So (A) matches with (s). SiO 2 is a tetrahedral molecule. Which is surrounded by four oxygen leading to tetrahedral shape. So (B) matches with (r). CO 2 is linear covalent molecule. In this carbon is connected to oxygen in linear fashion and form bond after sharing electrons between carbon and oxygen. Thus, (C) matches with (q). So finally, Column A Column B A BCl 3 s Planar trigonal molecule B SiO 2 r Tetrahedral molecule C CO 2 q Linear covalent molecule
