Question

5 valid reasons for low % yield during experiment of hydroboration/oxidation of alpha-pinene.

Answer 1

Reaction ch B43, "THE L. pinene Na Bo₂.4460 7 ho 3.OM - Reasons for low yield: Punt of slacking compound : L I starting compound is not 100% puce then yfed of product decreases. 2) pucity of reagent: If purity of dibodane of further oxldising agent is nor high then yled of product decreases. Temperature / reaction condition Each reaction occurs at a pericular conditime I we did not use an optimum condition then yield of product decreases. 4) Weighing of sample & reagent An appco pricate amount of reagent & shauling compounds are necessary for reaction. Heither more not less compounds are taken otherwise side reactions occurs & yield of product decreases s last most important factor is after completion. of reacion extacHon pu &fication procedure must be lollow with standaad techniques so that loss of product decreases
