Silicon is the second most abundant element (~27.2%)in the earth's after oxygen (45.5 %) Carbon. Silicon, germanium, tin and lead constitute the group 14 of the periodic table. Chemistry of silicon is distinctly different from that of carbon. For example, under standard conditions CO_(2) is a gas whereas SiO_(2) is a covalent solid. Draw the structure of the anion present in pyroxene (MgCaSi_(2)O_(6)). Silicones are important synthetic polymers which find extensive applications due to their chemical inertness and water repelling nature. Thet are produced via the following reactions. 2 C_(6)H_(5)Cl +Si underset("370 K")overset("Cu")to A A underset(-HCl)overset(H_(2)O)to B
