    In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR 2 OH”, where “R” indicates a carbon-containing group. Examples of primary alcohols include ethanol and 1-butanol. Methanol is also generally regarded as a primary alcohol, [2] [3] including by the 1911 edition of the Encyclopædia ...

    CH 2 =CH 2 + 3 O 22 CO 2 + 2 H 2 O, ΔH=−1327 kJ/mol (CH 2 CH 2)O + 2.5 O 22 CO 2 + 2 H 2 O, ΔH=−1223 kJ/mol. According to a kinetic analysis by Kilty and Sachtler, the following reactions describe the pathway leading to EO. In the first step, a superoxide (O 2 −) species is formed: [73] O 2 + Ag → Ag + O 2 −. This species ...
