Question

because it is 3° carbon shouldnt it be an SN1 reaction? even though it is in a aprotic solvent with a strong Nu?

Sodium Cyanide reacts with 2-bromobutane in dimethylsulfoxide to form a substitution product. Identify the configuration of the 2-bromobutane structure shown below. Then draw the substitution product formed when this enantiomer reacts with NaCN in DMSO, and indicate the stereochemistry of the product. O O (R)-2-bromobutane (S)-2-bromobutane Use wedge-and-dash bonds to show stereochemistry, and show explicitly the hydrogen on any asymmetric carbon The substitution product is: OR нс- NaCN DMSO O O racemic achiral the praction figura Incorrect The aprotic polar solvent favors an SN 2 reaction, leading to inversion of configuration For comparison, an SN1 reaction leads to racemization
