Interpretation The reasons why methanol and ethanol are soluble in water whereas octanol is poorly soluble have to be determined. Concept introduction: ‘Like dissolves like’ principle said that polar compounds including ionic compound should be more soluble in polar solvent. Likewise, non-polar compound should be more soluble in non-polar solvent. Other hand, compounds with similar intermolecular force capability to soluble in one another because solute-solvent interactions are similar signification to the solute-solute interaction. ‘ The set of repulsive and attractive force between molecules that result from the polarity between neighboring molecules is represented as intermolecular force. There are four types of intermolecular forces: Hydrogen bonding London dispersion force Ion – dipole force Dipole – Dipole force Hydrogen bond: Hydrogen is bonded to strong electronegative atom like oxygen, nitrogen etc.

Draw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant rate under these conditions, check the box underneath the drawing area instead. Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products. Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but strong heat or reflux is not used. Cl Substitution will not occur at a significant rate. Explanation Check :☐ O-CH + Х Click and drag to start drawing a structure.
