Individual Reactions

Hydrogen bromide (g) + CH3BrMg (solution) = Methane (solution) + Br2Mg (solution)

By formula: HBr (g) + CH3BrMg (solution) = CH4 (solution) + Br2Mg (solution)

Quantity Value Units Method Reference Comment
Deltar-274.5 ± 2.2kJ/molRSCHolm, 1981solvent: 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

magnesium (cr) + Methane, bromo- (l) = CH3BrMg (solution)

By formula: Mg (cr) + CH3Br (l) = CH3BrMg (solution)

Quantity Value Units Method Reference Comment
Deltar-267.8 ± 4.4kJ/molRSCHolm, 1981solvent: 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) + Methane (solution) = Pentane (solution) + CH3BrMg (solution)

By formula: C5H11BrMg (solution) + CH4 (solution) = C5H12 (solution) + CH3BrMg (solution)

Quantity Value Units Method Reference Comment
Deltar-15.1 ± 4.2kJ/molRSCHolm, 1983solvent: Diethyl ether
