Question

THEORY electrophiles (X-Y) will add across the double bond of an alkene to yield a saturated compound. If bromine (Br is the electrophile, the resulting compound is a 1,2-dibromide (also called a vicinal dibromide) (2). C C X-Y (1) (2) C C Br Br Br 1,2-dibromide vicinal dibromide Typically, electrophilic brominations of alkenes are carried out in methylene chloride (CH2Cl2 or carbon tetrachloride (CCl These solvents are ideal because they are non-reactive and will not interfere with the desired reaction. However, both solvents are volatile and toxic and both are suspected carcinogens. The traditional reagent used for these brominations, Br2, is also dangerous to handle because it is highly corrosive and causes severe burns upon contact with the skin. In this experiment, you will brominate (E e using alternative reaction conditions pyridinium tribromide in ethano (EtOH)

Explanation / Answer

In situ in chemistry means preparation of something on site, it means the production of a reagent in reaction mixture due to the instability of the reagent or reactivity.

Here the reagent that is being prepared on site is Br2, because it is highly reactive and unstable
