Title: organic chemistry reaction
Post by: ashwinkandel on October 01, 2010, 12:38:51 pm
can anyone give me the molecular formula of the compound formed when Bromine reacts with following compound:

Bromine will react with the compound by electrophilic substitution mechanism.

All the double bonds will be broken and each carbon forming the carbon-carbon double bond will take a bromine atom.

Hence formula will be  :
CH3C(Br)CH3CHBrCH2CH2C(Br)CH2BrCHBrCH2BR

I know its damn difficult to follow that but just add a bromine atom to each carbon forming the carbon-carbon double bonds and you'll get your answer :)

one more question . is the reaction electrophillic substitution or electrophillic addition?

yeah.......it's addition.

That was just a petty mistake from my part and I apologise for that :)
