Question about optical isomer notation | ||||||
I am confused about the (+) and (-) abbreviations for describing optical isomers. The abbreviation page on this site indicates that (-) is dextro and (+) is levo. However, in other chemistry-related web sites and books that I have read, (+) is dextro and (-) is levo. Who is correct? |

Dextro - light rotates clockwise Levo - light rotates anti-clockwise So that makes dextro (+) and levo (-) Hope that helps. Where is the page that says dextro is (-)??? -AC Its just my opinion, but no-one listens to me anyway, and rightly so... |
