No change is FTIR analysis.
InfraRed (IR) spectroscopy will give information about functional group information;
In reacemic mixture; compound doesn't change any functional group attachment. It is only about the spatial (3-Dimensional) arrangement of groups/atoms.
So; functional group information doesn't changes for recemic mixture.
Will a racemic mixture have the same FTIR analysis as a pure enantiomer?

11. Enantiopurity - How pure a substance is in one enantiomer over the other is expressed as a % enantiomeric excess. Consider the following theoretical scenario: CH2OH CH2OH optical rotation: +100° optical rotation: -100° % composition % enantiomeric excess observed rotation In the lab, a polarimeter can give you optical purity (% enantiomeric excess) by comparing against a pure enantiomeric standard: Optical purity = specific rotation of sample - X 100 specific rotation of pure enantiomer Page 2 A mixture...
Thermolysis of racemic-1 establishes an equilibrium with 2 as shown. If a chiral version of 1 were used, what would be the stereo chemical characterization of 2? Select one: A racemic mixture of enantiomers. A single enantiomer. A mixture of disaster embers, each one of which is a single enantiomer. A mixture of disaster embers each one of which is a racemic compound.
Which statement is true about a racemic mixture? TV Select one: O a. The specific rotation equals zero ob. Both enantiomers are present in equal amounts O c. The bp of the racemic mixture is equal to the bp of the pure enantiomers Od. All of the above
Which of the following is true about any (R)-enantiomer? a. It is dextrorotatory. b. It is levorotatory. (R) indicates a racemic mixture. It is the mirror image of the (S)-enantiomer. It is an equal mixture of + and –
what is the %ee of a mixture of enantiomer that contains 27% of the “R”enantiomer?
If acetophenone was reduced using NaBH4 rather than CBS reagent, a racemic mixture of (±)-1-phenylethanol would be obtained. How would you isolate pure R-(+)-1-phenylethanol from this mixture?
