Concept explainers
(a)
Interpretation:
The rotation of R-lactic acid as to be predicted.
Concept introduction:
Enantiomer has asymmetric centers, so it shows optical activity.
If Enantiomer that rotates plane polarized light in counterclockwise direction, then it is called levorotatory.
If Enantiomer that rotates plane polarized light in clockwise direction, then it is called dextrorotatory.
Pair of enantiomers has different optical activity, which means if one will show levorotatory then the other will show dextrorotatory.
(b)
Interpretation:
The rotation of R-sodium lactate as to be predicted.
Concept introduction:
Enantiomer has asymmetric centers, so it shows optical activity.
If Enantiomer that rotates plane polarized light in counterclockwise direction, then it is called levorotatory.
If Enantiomer that rotates plane polarized light in clockwise direction, then it is called dextrorotatory.
Pair of enantiomers has different optical activity, which means if one will show levorotatory then the other will show dextrorotatory.

- Why is it not advisable to use aqueous hydrochloric acid in a Grignard reaction of a ketone? A) The Grignard reagent will react with the acid and cannot react with the ketone. B) The ketone will be protonated and will become unreactive. C) The ketone will form an unreactive enol.
