>In the addition of HCN, NaHSO 3 , RMgX etc to carbonyl compounds the groups on the carbonyl compound that increases the positive charge on the carbonyl atom (i.e., electronegative group) will increase its reactivity towards the addition and vice versa. The order of reactivity i..

Water - About 70-73% of earth is covered by water. Water is available in the form of oceans, seas, rivers, lakes, ponds, pools, polar ice caps and water vapour. The main component of hydrosphere is water. Water exists in all the three forms i.e., solid (snow), liquid (water) and gas (wate..

In the Earth's biosphere, water is essential to all forms of life. Interestingly, it is also the biospheres most abundant compound and a unique substance from the chemical point of view. About 75% of the Earth's surface consists of water. Water is present as either (a) Solid - ice, snow e..
