Question

How do you account for the racemization of
(+)-2-iodobutane when it is allowed to react with
iodide ion ?​

Answer 1

Answer:

with the help of sn1 equation

Answer 2

The account for the racemization of(+)-2-iodobutane when it is allowed to react with iodide ion is due to the SN2 reaction .

• Racemization is defined as the process in which there is zero optical activity and wherein optically active compounds (which consist of only one enantiomer) are converted into an equal mixture of enantiomers .

• Here, (+)-2-iodobutane is reacted with iodide ion like NaI , as I- is a good leaving group due to big size of iodine so charge will dispersed well on it and it will become stable . So, here the repeated SN2 reactions occur which will result in the racemization mixture of (±)-2-iodobutane .
