This study describes the influence of mass transfer on the steady two-dimensional magnetohydrodynamic (MHD) boundary layer flow of a Jeffery fluid bounded by a stretching sheet. A uniform magnetic field in the presence of chemical reaction is applied. The arising non-linear partial differential equations are reduced to non-linear ordinary differential equations by similarity variables. Similar solutions of velocity and concentration fields are derived by a homotopy analysis method (HAM). The values of surface mass transfer and gradient of mass transfer are also tabulated.
