Question

What changes would be made to separate the two isomeric pinene (α and β), bp 156 oC and 167 oC 
respectively that are the major constituents of commercial turpentine?

Expert Solution
Step 1

As the boiling points of the isomers is different enough that we can separate them by fractional distillation. There is difference of 11°C present in alpha pinene and beta pinene.So, by changing temperature we can separate alpha pinene and beta pinene
