We have focussed to study the even-denominator fractional quantum Hall(EDFQH) states observed in monolayer graphene. In this letter, we have studiedpolarization mainly for the two EDFQH states at filling fractions $\nu = 1/2,1/4$, which are observed in an experimental study [Nat. Phys. 14, 930 (2018)] afew years ago. We have applied Chern Simon's gauge field theory to explain thepossible variational wave functions for different polarized states andcalculated their ground state energies using the Coulomb potential. We havechosen the lowest energy states using suitable combinations of flux attachedwith the electrons for different polarized states of those EDFQH states.
