What is a meso compound in organic chemistry? What does "single-bonded" and "double-bonded" mean in organic biology? What makes organic chemistry different from other areas of chemistry? What does aq mean in chemistry? What is meant by reflux in organic chemistry?
Lectins are a defense mechanism which all life forms appear to have. Essentially, they are a low level toxin. The purpose of lectins is to discourage other animals from eating that life form. By triggering a negative reaction in the predator, that life form is then viewed as an undesirable ...
35 parts of hexamethylene bis-dicyandiamide, 35 parts of p-chloroaniline hydrochloride and 250 parts of β-etoxyethanol are stirred together at 130- 140°C for 2 hours under reflux. The mixture is then cooled and filtered. The solid is washed with water and crystallised from 50% aqueous acet...
A reflux condenser is a piece of laboratory glassware that's used to cool vapors. It's made up of a glass tube encased in a glass...

This large-scale distillation is carried out in large cylindrical shaped towers known as fractionating columns. The usual range of width of these columns id around 0.6m-6m. The high efficiency of these towers is because of the use of reflux. Reflux is basically the fraction of the condensed ...
