isomers!

yaar 6 geometrical isomers are possible in this case..

Draw the structure urself by usin
on one carbon place Br and F then in one case I will be trans to Br and in other case Cl is trans to Br..
similarly place Br and Cl on one carbon..then in one case I will be trans to Br and in other case F is trans to Br..
then place Br and I on the same carbon then in one case F will be trans to Br and in other case Cl is trans to Br..

there are 3 geometrical isomers

Optical isomers???...how yaar..none of the carbon is chiral here..

yes im sorry didnt see it properly
