Question

Please draw out the complete mechanism for this reaction - including each step and electron movement with arrows. Also, explain in simple term - yet in detail - the analytical method(s) mentioned in the screenshot.

Titrimetric Determination of the Epoxide Content 2,3-Epoxypropyl-N-alkyl-N,N-dimethylammonium chlorides (epoxides) react in aqueous solutions with hydrochloric acid saturated with magnesium chloride to the corresponding chlorohydrins. OH t cr + HCIMgCI, The excess acid is back-titrated with sodium hydroxide and the end point is determined either potentiometrically or through color change of a methyl red indicator solution.
