Title: Acetanilide Synthesis Objective: To synthesize Acetanilide by recrystallization. To check its purity by calculating its percent yield. Introduction: Aniline is a primary aromatic amine and weak base which forms salts with mineral acids. In acidic solution‚ nitrous acid converts aniline into a diazonium salt that is an intermediate in the preparation of a great number of dyes and other organic compounds of commercial interest. When aniline is heated

Introduction There is a saying that states ‘one either lives to eat or eats to live’ and Italy as a country is ruled by the former. Italy is a culture that is rich and saturated in their traditions of cooking. They take pride in their food and live by the credo that food is only used if it is fresh‚ local and in season. There has been much debate on what defines Italian food and through research one can see that Italian food is not typical of a specific dish‚ rather that each region offers a new

thus the aldehyde reacts with itself to yield a product. The product formed in an aldol condensation contains and adehydes and an alcohol. Claisen-Schmidt condensation is a crossed aldol condensation that involves an aromatic aldehydes dehydration to yield double bond conjugated aromatic ring and the carbonyl group. Aldol products can dehydrate under either acidic or basic conditions to give‚ α‚ β-unsaturated aldehydes and ketones. Although there is even balance in the equilibrium in aldo condensation

acceptors. The presence of N–H dipoles allows amides to function as H-bond donors as well. Therefore‚ atenolol is the most polar drug and can be assigned the lowest log P value i.e. 0.16. Propanolol is the least polar drug because it contains non-polar aromatic functional group. Benzene is rendered non-polar due to its high structural symmetry of pi system of p-orbitals that distributes the charge equally along the ring. Therefore‚ propranolol can be assigned the highest log P value i.e. 3.21. Metoprolol
