Match the compounds listed in column I with characteristic listed in column II. {:("Column-I","Column-II"),((A)"Cyclic silicates",(p)"Tetrahedral hybridisation"),((B)"Single chain silicates",(q)"Si-O bonds are 50% ionic and 50% covalent"),((C )"Pyro silicates",(r)"General formula is")(SiO_3)_n^(2n),((D)"Sheet silicates (two dimensional ",(s)"Two oxygen atoms per tetrahedron are shared "),(,(t)"Square planar geometry"):}

Answer»


Solution :(A)Two OXYGEN atoms per tetrahedron are shared forming rings.`(SiO_3)_n^(2n-)`.HYBRIDISATION of each SI is `sp^3`.
(B)Two oxygen atoms per tetrahedran are shared forming a chain of tetrahedron, `(SiO_3)_n^(2n-)`, Hybridisation of each Si atom is `sp^3`.
(C )One oxygen atom per tetrahedron is shared . `Si_2O_7^(2-)` .Hybridisation of each Si atom is `sp^3`.
(D)Threeoxygen atom per tetrahedron is shared . `(Si_2O_5)_n^(2-)` .`sp^3` hybridisation .
