– Br ▁bond ▁is ▁a ▁common ▁functional ▁group ▁that ▁forms ▁part ▁of ▁core ▁organ ic ▁chem istry . ▁Form ally , ▁comp ounds ▁with ▁this ▁functional ▁group ▁may ▁be ▁considered ▁organ ic ▁derivatives ▁of ▁the ▁b rom ide ▁an ion . ▁Due ▁to ▁the ▁difference ▁of ▁electron eg ativity ▁between ▁b rom ine ▁( 2 . 9 6 ) ▁and ▁carbon ▁( 2 . 5 5 ), ▁the ▁carbon ▁in ▁a ▁C – Br ▁bond ▁is ▁electron - def ic ient ▁and ▁thus ▁elect roph il ic . ▁The ▁react ivity ▁of ▁organ ob rom ine ▁comp ounds ▁res emb les ▁but ▁is ▁intermediate ▁between ▁the ▁react ivity ▁of ▁org ano ch lor ine ▁and ▁org ano iod ine ▁comp ounds . ▁For ▁many ▁applications , ▁organ ob rom ides ▁represent ▁a ▁comprom ise ▁of ▁react ivity ▁and ▁cost . ▁ ▁Organ ob rom ides ▁are ▁typically ▁produced ▁by ▁add itive ▁or ▁subst it utive ▁b rom ination ▁of ▁other ▁organ ic ▁prec urs ors . ▁B rom ine ▁itself ▁can ▁be ▁used , ▁but ▁due ▁to ▁its ▁to x icity ▁and ▁vol at ility ▁sa fer ▁b rom in ating ▁re ag ents ▁are ▁normally ▁used , ▁such ▁as ▁N - b rom os u cc in im ide . ▁The ▁principal ▁re actions ▁for ▁organ ob rom ides ▁include ▁de h ydro b rom ination , ▁Gr ign ard ▁re actions , ▁re duct ive ▁coupling , ▁and ▁nucle oph il ic ▁substitution . ▁ ▁Organ ob rom ides ▁are ▁the
