Calculate the EF and MF from the following data using the \(A_{r}\) values: \(\mathbf{C}=12.01, \mathrm{H}=1.008\) \(\mathrm{N}=14.01, \mathrm{O}=16.00, \mathrm{Cl}=35.5\) (a) \(\mathrm{C}, 54.86 ; \mathrm{H}, 13.51 ; 0,21.62 \%\) LRMS \(M_{\mathrm{r}}=74\) (b) \(\mathrm{C}, 53.33 ; \mathrm{H}, 11.11 \% \operatorname{LRMS} M_{\mathrm{r}}=90\) (c) \(C, 54.55 ; \mathrm{H}, 9.09 \%\) LRMS \(M_{\mathrm{r}}=88\) (d) C, 56.25; H. 3.90; Cl, 27.34\% LRMS \(M_{\mathrm{r}}=128\)
