WebJul 31, 2024 · In more dilute acid, the rate picks up because there is more free RNH 2 in solution. Dehydration of the aminoalkanol (Equation 16-6) is acid catalyzed; this reaction normally is fast at pH values smaller than 3-4. Therefore, the slow step at pH < 4 is … WebThe reaction of C 6 H 5 CHO with Co 3+ must certainly be independent of the oxygen pressure. The kinetics in glacial acetic acid were investigated (in the absence of oxygen) by measuring the amount of Co 2+ accumulating. The reaction was found to be bimolecular, with a rate-constant of 3·5 × 10 −26 cm 3 molecule −1 sec −1 at 26°C. The agreement … Webthe reaction is first-order with respect to the iodate ion concentration and the times clearly reflect this, the idea of first-order reactions can be developed through discussion.

Webmore. In a substitution reaction an existing group on the substrate is removed and a new group takes its place. In an elimination reaction the group is simply removed and no new group comes to take its place and this usually results in a double or triple bond forming in the substrate instead. Hope that helps. Comment. Bisulfite sequencing applies routine sequencing methods on bisulfite-treated genomic DNA to determine methylation status at CpG dinucleotides. Other non-sequencing strategies are also employed to interrogate the methylation at specific loci or at a genome-wide level.
