Answer:

See explanation

Explanation:

Biphenyl is formed by the reaction of two phenyl radicals. It is a major impurity ( undesired product) that is formed when some amount of phenyl bromide (bromobenzene) doesn't react solid magnesium in the formation of the Gignard reagent. In other words, it is formed when there is a coupling reaction between Grignard reagent  (Grignard reagent acts as a strong nucleophile) and bromobenzene

Biphenyl is usually produces when the concentration of bromobenzene is high and when there is increase in temperature during reaction. To minimize the amount of biphenyl, it is best to add the bromobenzene solution slowly so that the reaction boils gently, since the reaction is favorable at low temperatures.

How did rearmament impact Germany's power in comparison to other European nations ?
Vilka [71]

Answer:

When Nazi Germany openly started re-armament in 1935, few should have been surprised as Hitler had made it very clear both in his speeches and in “Mein Kampf” that he would break the “unjust” terms of the Treaty of Versailles.

Explanation:

Hitler saw Nazi Germany as being at the centre of Europe and as the great power of Europe, the nation needed a strong military. Throughout the 1920’s, Germany had been technically keeping to the terms of the Treaty of Versailles but in reality she had been bending the rules regarding training. Versialles had not stated that Germany could not train submarine crews abroad or that pilots for the banned German Air Force could train on civilian planes. Therefore, on paper Hitler inherited a weak military but this was not in reality the case. However, Hitler knew that publicly Nazi Germany was still seen within Europe as being held to the terms of Versailles and he was determined to openly break these terms and re-assert Germany’s right to control its own military.

hope this help plz mark branly if it does :P
