1. Diamond is the purest form of carbon. 2. It is the densest of all allotropes of carbon (specific gravity is 3.51). 3. Diamond's tetrahedral structure, makes it the hardest naturally occurring substance. It is brittle and transparent. 4. Pure diamond is colourless, but traces of dissolved impurit..
c) Hydroboration
Alkenes react with diborane (B 2 H 6 ), which is an electron deficient molecule to yield alkylboranes (R 3 B). These are oxidised to alcohols on reaction with hydrogen peroxide in presence of alkali. In each addition step, the boron atom is attached to the sp 2 carbon atom that is bonded to h..

The radio horizon for space waves is about four-thirds as far as the optical horizon. This beneficial effect is caused by the varying density of the atmosphere, and because of diffraction around the curvature of the Earth. The radio horizon of an antenna is given, with good approximation,..
