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.

Answer: Heat, dot of light flashing by, explosion
Explanation: In an article published by the New York times and written by Ellen Barry and Andrew E. Kramer on February 15th, 2013, titled, "Shock Wave of Fireball Meteor Rattles Siberia, Injuring 1,200."
A blogger named Darya Frenn that experienced the event was quoted to have written “I opened the window from surprise — there was such heat coming in, as if it were summer in the yard, and then I watched as the flash flew by and turned into a dot somewhere over the forest, And in several seconds there was an explosion of such force that the window flew in along with its frame, the monitor fell, and everything that was on the desk.”
From the excerpt above, it can be deduced that the order in which he experienced the event was
1) Heat,
2)dot of light flashing by, 3)explosion.
