Define how the acetonide derivatives of the isomers

Reference no: EM13565492

1) For the 9.42 mmol of benzoin, what is the minimum amount (in mmol) of NaBH4 needed for this reduction? (look at balanced equation)

2) Why use 10.6 mmol of NaBH4

3) Are equal amounts of erythro (S, R) and threo (R,R) diols produced? if not, why?

4) 60 MHz HNMR cannot distinguish between erythro (S,R) and threo (R, R) diols. Explain how the acetonide derivatives of these isomers can easily be distinguished by 60 MHz HNMR (include structural diagrams in the explanation).
