The trend of melting point for the given alkyl halides is to be explained. Concept Introduction: The magnitude of dispersion forces depends upon how easily electron in the atom or molecule polarized in response to a dipole. Due to a larger size of the electron cloud, greater dispersion force is observed as electron are less tightly held by the nucleus. If other factors is same dispersion forces increases with molar mass. The polar molecule containing a hydrogen atom that is directly bonded to high electronegative atom fluorine, nitrogen or oxygen exhibit additional interaction called hydrogen bonding.

Calculating the pH at equivalence of a titration Try Again Your answer is incorrect. 0/5 a A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of hydrocyanic acid is 9.21. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added. pH = 11.43] G 00. 18 Ar B•
