Q. Determine the equilibrium constant?
At 298 K, the molar conductivities at infinite dilution of NH4Cl, NaOH and NaCl are 129.8,217.4 and 108.9 ohm-1 cm2 mol-1 respectively. If the molar conductivity of centinoram solution of NH OH is 9.33 ohm-1 cm-1 determine the equilibrium constant.
Effects of substituents on the acidity of phenols: Existence of electron attracting group, (for example -NO 2 , -X, - NR + 3 , -CN, -CHO, -COOH) on the benzene ring increases
Q. Show Bond Lengths and p Π - d Π bonding? The bonds between S and 0 are much shorter than expected for a single bond in its oxides and therefore, may be considered as doubl
