*Allylic bromination is the addition of a bromine atom to the allylic position of a double bond rather than to the double bond itself. The most common reagent used for allylic bromination is N-bromosuccinimide (NBS). Bromine molecule usually adds across the double bond to form an adduct.
*An adduct is a product of the addition of 2 or more distinct molecules containing the atoms of all the added molecules.
*Here the order of the names of the 10 molecules given is,
