How to find stability of carbocations in benzene ring..???How to find optically inactive isomers ??? (say of--C2H5Cl)How to find the weakest C-X (carbon-halogen bond in a benzene ring???? Solution) basically 3 degree carbocations are more stable as compared to 2 degree and one degree. for optically inactive isomer look for terms like racemic mixture and diastomers and the weakest halgon bond depends on leaving group halogen better leaving group weaker the bond
Formula of a metallic oxide is MO.The formula of its phosphate will be: (1) M 2 (PO 4 ) 2 (2) M (PO 4 ) (3) M 2 (PO 4 ) (4) M 3 (P
How many KCal of heat are liberated when 48.0 grams of iron are burned to form Fe2O3 at standard state conditions? (Change of Hf^0 of Fe2O3 is -197 kCal/Mole )

1 gm of a metallic oxide on reduction gives 0.68 gm of the metal. ans) Mass of metal/mass of oxygen=eq. mass of metal/eq. mass of oxygen. applying this we get .68/.32=x/8 x=1
