oh man . im no sure if your formulae is wrong. but if its correct theres a double double bond.  which definately does to have a chral centre thus optical isomer does not occur

Yes, C3H4BrI can have an optical isomer. The carbon marked with an asterisk is the chiral carbon. The systematic name for this compound is 3-Bromo-3-iodoprop-1-ene.
