In alcohol, the oxygen of the -OH group is attached to sp 3 hybridized carbon by a sigma ( s ) bond formed by the overlap of sp 3 hybrid orbital of carbon with an sp 3 hybrid orbital of oxygen. in alcohols is slightly less than the tetrahedral angle (109 o 28') In phenols the -OH gro..

Trends in Chemical Reactivity of Group 13 Elements - Unlike boron, the other members of the group are metallic and the electropositive character increases as we go down the group. All these elements in their compounds exhibit the oxidation state of + 3 and +1. The impo..

is a means by which electrical energy is transferred from one place to another for utilisation. Charges in motion constitute an electric current. We know from electrostatics that when an isolated conductor is placed in an electric field, the charges in the conductor rearrange themselves so that t..
