Diels Alder Reaction Sample
Change
Chemistry
The Diels-Alder Reaction is a reaction used in organic chemical science that builds rings really expeditiously ( 1 ) . this cycloaddition procedure allows for the stereoselective formation of cyclohexene rings possessing every bit many as four immediate stereogenic centres ( 3 ) . This reaction occurs without intermediates. in a individual measure. which explains…

The lab’s objective is to brominate trans-stilbene using a mixture of acetic acid and pyrimidium tribromide through refluxing. The resulting product’s purity will be determined by measuring its melting point, which is anticipated to be around 240 ºC. Furthermore, a flame test will be performed to observe a green-blue color. The following table presents the…

labnal groups were present in certain substance. The Benedicts test was used to identify reducing sugars (glucose and fructose) based on their ability to reuce the Capric ions to cuprous oxide at high pH. The Cuprous oxide is reddish orange in color when shown to be at high levels by the test, and greenish when…

Carbohydrate
Chemistry
Plant
Cotton is a soft fiber that grows around the seeds of the cotton plant . The fiber is most of the time spun into thread and used to make a soft but strong textile. Cotton is a valuable crop because only about 10% of the raw weight is lost in processing. Once natural wax, protein,…
Phytochemicals Found In The Tropical Pineapple Plant Biology
Biology
Chemistry
Pineapples can be eaten both fresh and processed although the proteolytic protein bromelain will degrade if it is processed, this means that if canned Ananas comosus is used to do gelatin it will put, but if fresh Ananas comosus is used the jelly will non put, besides if you use fresh Ananas comosus to cook…
