Naphthalene is soluble in ether orbenzene because. ?
Naphthalene is soluble in ether or benzene due to London dispersion forces (induced dipole-induced dipole attractions) between the non-polar solute and non-polar solvents. The strength of these intermolecular forces determines the solubility.
Which of the following is applicable for the solubility of gases in liquid
Concentration of lead metal in a blood of any person is more than that of 10microgram. $ dm^{-1} $ , than that person is considered as on effect of poision sectrion. Then calculate its concentration in ppb (parts per billion)
