How can you get acetone from CH_3MgI ?

The Arrhenius equation for trans ispmerisation of 2 -butene and 2 -butene nitrile are given as follows: (a) For 2 -butene CH_(3)CH = CHCH_(3)K(S^(-1)) = 10^(13.8) (b) For 2 -butene nitrile CH_(3)CH = CH.CNK'(S^(-1)) = 10^(11) exp^(-214.5 kJ "mol"-1//Rt) The temperature at which K = K'
