Write the isomers of the compound having formula C4H9Br.


Double bond equivalent is used to find the level of unsaturations present in an organic molecule.


DBE =


Where C= number of carbon atoms present


H=number of hydrogen atoms present


N=number of nitrogen atoms present


X=number of halogen atoms present


Double bond equivalent (DBE) for C4H9Br


=


=0


So none of the isomers has a ring or unsaturation, so the isomers are positions or chain isomers as shown below in the table:


Straight chain isomers



Branched chain isomers
