How it works – we’ll just discuss the alkyne reduction here for now, but reduction of the alkyne by sodium results in breakage of the C-C double bond and formation of an anion adjacent to a radical. The radical that is formed can interconvert between its cis and trans form, …

WitrynaSince step 1 limits the overall rate of the reaction, the rate law for this step will be the same as the overall rate law. The predicted rate law for the overall reaction is therefore. \text {rate} = k [\ce {NO2}]^2 rate = k[NOX 2]2. This rate law is in agreement with the experimentally-determined rate law we saw earlier, so the mechanism also ...

WitrynaThe alkali–silica reaction (ASR), more commonly known as concrete cancer, is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous (i.e., non-crystalline) silica found in many common aggregates, given sufficient moisture.. This deleterious chemical … WitrynaAnswer: When CH3CH2Br reacts with aqueous NaOH solution, CH3CH2OH is produced. This is a nucleophilic substitution reaction and follows SN2 pathway as the ethyl bromide is a primary alkyl halide. The nucleophile OH- attacks on the nucleophilic carbon atom from the back side and bromide starts to ...
