For the mass spectrum of B r 2 , the molecular species give peaks at m/Z ratios of 158, 160, and 162 are needed to be determined. Concept introduction: Mass spectroscopy: It is a form of spectroscopic technique which is used for the elucidation of the molecules, depending upon the mass of the molecule. Parent ion peak: It is defined as the prominent peak in the mass spectrum of the molecule which represents the not fragmented molecular ion in the given molecule with greater m/z value. Base peak: It is the tallest peak in the spectrum. B r 2 ionize to form positive ions, B r 2 + a n d B r + . Elements present in B r 2 are 79 B r a n d 81 B r .

A chemist titrates 120.0 mL of a 0.7191M dimethylamine ((CH3)2NH) solution with 0.5501 M HBr solution at 25 °C. Calculate the pH at equivalence. The
pk of dimethylamine is 3.27.
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 HBr solution added.

Alcohols can be synthesized using an acid-catalyzed hydration of an alkene. An alkene is combined with aqueous acid (e.. sulfuric acid in water). The
reaction mechanism typically involves a carbocation intermediate.
