hydrogen substitution. However‚ this is not thermodynamically favoured because a sp3 hybridized carbon is generated‚ which disrupts the cyclic conjugation. In order to regenerate the aromatic ring‚ a proton is lost at the sp3 hybridized carbon. Thus‚ p-Nitroaniline can be prepared by means of electrophilic aromatic substitution. To begin‚ nitric acid needs to be activated as it has little electrophilic power. Thus‚ concentrated sulfuric acid is added to protonate the nitric acid. Dehydration produces

“A&P” The story “A&P” gives us a interesting‚ dynamic protagonist. We are given a short situation in which to determine his personality and his intentions. As the story progresses‚ we get a peek of Sammy’s personality‚ but his reasons are still a blur. Several other characters assist to contrast against Sammy.

The Equilibrium Constant of an Ester Hydrolysis Reaction Jesus Flores March 30th‚ 2015 Abstract: This experiment was conducted in order to discover the Kc‚ equilibrium constant‚ of a hydrolysis reaction of an unknown ester #2‚ unknown acid‚ and alcohol #2 products. The first week consisted of creating the reaction mixtures in bottles‚ next was preparing a NaOH solution while neutralizing with KHP. The final week consisted of titrating the bottles with the NaOH solution prepared previously

For Acidic hydrolysis‚ SAC was found to be well susceptible to acid hydrolysis with 0.05 M HCl at 40 ˚C for 30 min caused about 8% reduction in the peak area of SAC (Fig.4a). While this mild condition didn’t affect VAL. While‚ nearly 27% was the reduction in SAC’s peak area when subjected to alkaline hydrolysis. This considerable decline in the peak area of SAC when subjected to 0.01 M NaOH at 40°C for 30 min revealed degradation products peaks appeared at 3.339 and 9.482 minutes (Fig.4b) and they
