(g) + CH3BrMg (solution) = (solution) + Br2Mg (solution)
By formula: HBr (g) + CH3BrMg (solution) = CH4 (solution) + Br2Mg (solution)
|rH°||-274.5 ± 2.2||kJ/mol||RSC||Holm, 1981||solvent: Diethyl ether; The enthalpy of formation was calculated using the assumptions and the auxiliary data in Holm, 1981, except for the organic compound, whose enthalpy of formation was quoted from Pedley, 1994|
(cr) + (l) = CH3BrMg (solution)
By formula: Mg (cr) + CH3Br (l) = CH3BrMg (solution)
|rH°||-267.8 ± 4.4||kJ/mol||RSC||Holm, 1981||solvent: Diethyl ether; Due to the possibility of side reactions, the enthalpy of reaction was not considered to be sufficiently reliable for deriving the enthalpy of formation of the Grignard reagent Holm, 1981|
C5H11BrMg (solution) + (solution) = (solution) + CH3BrMg (solution)
By formula: C5H11BrMg (solution) + CH4 (solution) = C5H12 (solution) + CH3BrMg (solution)
|rH°||-15.1 ± 4.2||kJ/mol||RSC||Holm, 1983||solvent: Diethyl ether|
