MOLECULE OF THE MONTH

CHEMIST DEAD AT AGE 65

It finally the last month of school meaning that both teachers and students will be experiencing an obsence amount of sleepless nights. So, the moulcule of the month is caffeine. Caffeine is a stimulant, which means it raises brain and nervous system activity. It also boosts the body's circulation of hormones like cortisol and adrenaline. Caffeine, in little dosages, can help you feel energized and concentrated.

He was born in the Russian city of Nizhny Novgorod and died in Moscow. Markovnikov attended Kazan University and majored in economics and chemistry. Markovnikov began his career at the University of Odessa. as a professor. He was the one who proposed Markovnikov's rule, which states that when adding a polar reagent to an unsymmetrical alkene, the positive component of the polar reagent is attached to the carbon wih the most hydrogen, while the negative part is linked to the carbon with the least hydrogen. Markovnikov also made an impact on organic chemistry by discovering carbon rings with more than six carbon atoms, as well as a ring with four carbon atoms.

Analytical Methods

CHEMISTRY GAMES TO KEEP ACTIVE

Naming EDITION

Caffeine can be analyzed using capillary electrophoresis and high performance liquid chromatography. Both techniques exhibited good linearity in the analyzed range. All determination coefficients were better than 0.9997. Capillary electrophoresis is an analytical technique that separates ions based on their electrophoretic mobility with the use of an applied voltage since caffine isnt neutral this is a good method. HPLC is a good anaylitical method because caffiene isn't volitile and caffiene isnt very sensitive.

HOW TO NAME ESTERS

Ethyl Propanoate

1.Nathasha from Orange walk: Hey the Voice of Chemistry why electro compounds aren't a class of organic compound?

Answer: Organic compounds are defined as those that contain organic molecules such as carbon, hydrogen, and oxygen. As a result, electro compounds are not classified as organic compounds.

1. Identify the oxygen that is bound to carbon on both sides and is part of the continuous chain. (There will be a carbonyl present on one side of this oxygen, but none on the other.)Bulleted list
2. Second, start counting the carbon chains on both sides of the oxygen you found in step one.
3. Then use the following format: [alkyl on side away from carbonyl] (space) [alkane on side with carbonyl]. Finally, alter the -e to -oate ending of the alkane on the same side as the carbonyl.
4. When an ester group is linked to a ring, it is referred to as a ring substituent.
5. Other substituents found on each side of the ester are identified similarly to those found on ordinary alkane chains. The only requirement is that the substituent name be placed on the part of the name that corresponds to the side of the ester it is on.

Step1

2.Jamie from city: Hey, I got the question below in a test and I still don't know the answer to this day can you please explain.

Step2

Hey Jamie, the answer is c. Diazonium salts are formed when an aromatic primary amine is treated with nitrous (NaNO2 + HCl) acid at 273–278 K. These diazonium salts finally hydrolyze to phenols when heated with water.

Step3

Ethyl Propanoate

3. Kristy from Dangriga: Hey the voice I am really struggling to find the name of the reaction that occurs when the Formation of aromatic ketone forms from benzene by CH3COCl .

Step 5

Answer: Hey, Friedal craft acylation form aromatic ketone. The desired ketone can be obtained by using the appropriate acid chloride. The process works with all types of ketones, though bulkier aryl acid chlorides may require a stronger/longer heating.

1-chloromethyl ethanoate
