Color reconnection (CR) mechanism in PYTHIA model has been reported to beessential to describe the flow-like collective effect observed in highmultiplicity $p$+$p$ and $p$+Pb collisions. In this work, we test thismechanism towards explaining the Forward-Backward multiplicity correlation(b$_{\mathrm {cor}}$) measurements in $p$+$p$ collisions at the LHC energies.Out of the three different CR schemes implemented in PYTHIA, (a) MPI based CR(default mechanism), (b) QCD based CR and (c) Gluon moved CR, we found that theQCD based CR scheme describes relatively better the ALICE measurements ofb$_{\mathrm {cor}}$ in $p$+$p$ collisions at $\sqrt{\mathrm s}$ = 0.9 and 7TeV. In addition, we have tuned the parameters of the default CR mechanism inPYTHIA to describe simultaneously the measured charged particle multiplicitypseudo-rapidity ($\eta$) distribution and b$_{\mathrm {cor}}$. We found that anaverage number of multipartonic interactions ($\langle N_{\mathrm {MPI}}\rangle$) between 2.5 to 3 and CR range between 0.9 to 2.5 best describes theexperimental data. Finally, we have presented a study using PYTHIA events for$p$+$p$ collisions at $\sqrt{\mathrm s}$ = 7 TeV which shows that the strengthof Forward-Backward mean transverse momentum correlation (b$^{\langlep_{\mathrm{T}}\rangle \langle p_{\mathrm{T}} \rangle}_{\rm {cor}}$) is found toincrease with CR in contrast to decrease of b$_{\rm {cor}}$ values with CReffect. Hence, simultaneously studying the b$^{\langle p_{\mathrm{T}}\rangle\langle p_{\mathrm{T}} \rangle}_{\rm {cor}}$ and b$_{\mathrm {\rm {cor}}}$ inthe experiments will help in establishing the arguments either in favour or indisfavour of CR effect in the measurements.
