The nitration of benzaldehyde is an example of an electrophilic aromatic substitution reaction‚ in which a proton of an aromatic ring is replaced by a nitro group. Many aromatic substitution reactions are known to occur when an aromatic substrate is allowed to react with a suitable electrophilic reagent‚ and many other groups besides nitro may be introduced into the ring. Although the reaction produced a low yield at the end‚ the yield is calculated from the reaction and limiting reagent. Keywords:

People who are really good friends of mine or good observers have noticed that I wear a dolphin ring on my left ring finger. I have had this ring since the summer of 2007. This ring is a souvenir from my favorite family vacation. Nine years ago‚ my family and I traveled to San Antonio‚ Texas. While we were there‚ we visited the river walk‚ the mall‚ the Alamo‚ Sea World‚ Six Flags‚ and the zoo. All of those destinations were fun and each has a story to tell‚ but my favorite one was our day at Sea

The basic structure of all the penicillins consists of a thiazolidine ring fused with a beta-lactam ring‚ creating a fundamental nucleus (also known as 6-amino penicillanic acid) crucial for their antibacterial activity. A wide variety of semisynthetic penicillins are produced by altering the composition of the side chains attached to this nucleus.The molecular formula of penicillin is C16H18N2O4S and weight of 334.39 g/mol‚ each base with a variable side chain‚ “R” that differentiates the penicillins
