The equivalent mass of the acid if 15 .6 mL of 0 .562 N sodium hydroxide is required to titrate a solution prepared by dissolving 0 .631 g of an unknown acid is to be predicted. Concept introduction: Normality is defined as the number of equivalents of solute per unit volume of the solution. Equivalent mass is the mass of the compound per equivalent. One equivalent of any substance means it would react with or supply one mole of electron or protons in a reaction.

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.
