1.boron trichloride is trigonal planar, while aluminium chloride is tetrahedral in dimeric state. explain. 2.explain why silicon tetrachloride is readily hydrolised,but carbon tetrachloride is not. 3.why is nitrogen inert at room temperature? 4.calcium chloride and calcium fluoride are ionic compounds. but the former is highly soluble in water while the latter is sparingly soluble. 5. ammonia is acovalent compound, still it is highly soluble in water giving a basic solution but it is nearly insoluble in benzene. sorry for the whole lot of questions. but i am weak in chemistry. so please help.

Dear Aritra,

 The differing rates of hydrolysis are attributed to the greater atomic radius of the silicon atom, which allows attack at silicon. 

Nitrogen has five electrons in its outer shell and is therefore trivalent in most compounds. The triple bond in (N2) is one of the strongest in nature, making it relatively inert at and standard pressure. The resulting difficulty of converting (N2) into other compounds, and the ease (and associated high energy release) of converting nitrogen compounds into elemental N2, have dominated the role of nitrogen in both nature and human economic activities

Best Of Luck...!!!!
