The enantiomer of $\alpha-\mathrm{D}-(+)$ -glucose is

The enantiomer of $\alpha-\mathrm{D}-(+)$ -glucose is
  1. $\beta-\mathrm{D}-(+)$ -glucose
  2. $\alpha$ -D- $(-)$ -glucose
  3. $\alpha$ -L- $(-)$ -glucose
  4. $\beta-\mathrm{L}-(-)$ -glucose

Solution

In the D family the more dextrorotatory anomer is named $\alpha-\mathrm{D}-.$ In the $\mathrm{L}$ family the more laevorotatory anomer is named $\alpha \mathrm{L}$ ,
