Write the IUPAC Name of CH3CH2COCL

Explanation

i) `Fe_((s))|Fe^(2+)(0.001M)||H^(+)(1M)|H_(2)(g)(1" bar")|Pt(s)`
Cell reaction : `Fe_((s))+2H_(eq)^(+)rarrFe_((aq))^(2+)+H_(2)(g)`
`=[0-(-0.44)-(0.0591)/(2)log""(10^(-3))/((1)^(2))]=0.44-(0.0591)/(2)xx(-3)`
`0=0.44+0.0887=0.523V`
ii) `Sn(s)|Sn^(2+)(0.050M)||H^(+)(0.02)|H_(2)(g)(1" bar")|Pt(s)`
Cell reaction : `Sn(s)+2H_((aq))^(+)rarrSn_((aq))^(2+)+H_(2)(g)`
`E_("cell")=E_("cell")^(@)-(0.0591)/(n)log""([Sn^(2+)])/([H^(+)]^(2))`
`=[0-(-0.14)]-(0.0591)/(2)log""(0.05)/((0.02)^(2))`
`=0.14-(0.0591)/(2)xx(2.097)`
`=0.14-0.0620=0.08V`
iii) `Pt_((s))|Br_(2(s))|Bbarr(0.010M)||H^(+)(0.030M)|H_(2(g))("1 bar")|Pt(s)`
Cell reaction : `2Br^(Theta)+2H^(+)rarrBr_(2)+H_(2)`
`E_("Cell")=E_("Cell")^(@)-(0.0591)/(2)log""(1)/([Br^(-)]^(2)[H^(+)]^(2))`
`=(0-1.08)-(0.0591)/(2)log""(1)/((0.01)^(2)xx(0.03)^(2))`
`=-1.08-(0.0591)/(2)log(1.111xx10^(7))`
`=-1.08-(0.0591)/(2)(7.0457)`
`=-1.08-0.208=-1.288V`
