Question
Chapter 1, Problem 63EQ
Interpretation Introduction
Interpretation:
The anion formed after breaking C-Mg bond is to be identified
Concept Introduction:
During heterolytic bond cleavage, the more electronegative atom acquires the shared pair of electrons and turns out to be anion while the less electronegative element turns out to be cation.

4,4'-DIBROMOBIPHENYL
Robert E. Buckles and Norris G. Wheeler1.
1. Procedure
In a 15-cm. evaporating dish is placed 15.4 g. (0.10 mole) of finely powdered biphenyl (Note 1). The dish is set on a porcelain rack in a 30-cm. desiccator with a 10-cm. evaporating dish under the rack containing 39 g. (12 ml., 0.24 mole) of bromine. The desiccator is closed, but a very small opening is provided for the escape of hydrogen bromide (Note 2). The biphenyl is left in contact with the bromine vapor for 8 hours (or overnight). The orange solid is then removed from the desiccator and allowed to stand in the air under a hood for at least 4 hours (Note 3). At this point, the product weighs about 30 g. and has a melting point in the neighborhood of 152°. The crude 4,4'-dibromobiphenyl is dissolved in 75 ml. of benzene, filtered, and cooled to 15°. The resulting crystals are filtered, giving a…
