electron-donating groups

Welcome to Chem Help ASAP. Let’s focus on one type of R-group that we commonly encounter on aromatic rings, the electron-donating group. [turn page] In the upper right, we see a recap of the previous video. Electron-donating groups (or EDGs) are R-groups that behave both as ortho,para-directors and activators. Great! – but what are the […]

Stepping through the Shikimate Pathway II

We ended the last webcast, Part 1 of the shikimate pathway, by showing how the three building blocks came together and produced this molecule enolpyruvate shikimate phosphate, and now we want to see how this transforms first into prephenate and then from there to the aromatic amino acids phenylalanine and tyrosine. So we have to […]

Tests for Amines – MeitY OLabs

Tests for Amines Amines are derivatives of ammonia in which one or more hydrogen atoms are replaced by alkyl or aryl groups. When one of the three hydrogen atoms is replaced by alkyl or aryl group, primary amine is formed. When two of the three hydrogen atoms are replaced by alkyl or aryl group, secondary […]

Pencil Trick for Primary, Secondary, Tertiary, & Quaternary Carbon and other Atoms

Leah here from leah4sci.com and in this video I’m going to show you the pencil trick to quickly and easily identify primary, secondary, tertiary, quaternary, carbon and other atoms. Let’s start with carbon atoms. When you’re looking at a molecule if you see a carbon atom bound to other atoms, the way you classify this […]

Amine, Aniline and Amide Reactions – Organic Chem

Hi everyone this is Maverick Puah the Chemistry Guru. Now in this video we want to go through the must-know reactions of nitrogen compounds. in total we will have 3 reactions of amines, 3 reactions of phenylamines and 3 reactions of amides now first let’s talk about the reactions of amines. Now first must-know reaction […]

cleavage of ethers with acid

Good day from Chem Help ASAP. Ethers are extremely stable functional groups, but they certainly are not inert. Let’s see how these functional groups can be forced to react. [turn page] We have two reactions on the screen that result in the breaking of a C-O bond and thereby destroy the ether functional group. Both […]

Ch 21 Aldehydes and ketones 4 – Reactions with amines and water

The next reaction that we’ll look at are reactions with primary amines. So the same process goes into solving this as goes into solving nearly all the reactions and that is we first figure out “who has electrons?” Amines typically have a free lone pair of electrons that can react. And “who wants electron?”s or […]

ethers & other organic solvents

Welcome to Chem Help ASAP. Because ethers are fairly unreactive, they are often used as reaction solvents. [turn page] In teaching organic chemistry, I tend to focus more on reagents and transformations. The solvent is a detail that I often skip because we can only handle so much information for each reaction. Solvents, however, are […]

Organic Molecules: The versatility of carbon–The tremendous variety of organic compounds on earth.

hello and welcome to a primer on organic chemistry There is something very interesting about all the different molecules that exist on earth which is that the vast majority of them contain carbon something extremely important to remember is that we call compounds that contain carbon organic compounds all of which will answer our overarching […]

Question 7 IUPAC Nomenclature of Alkanes, Halides, Amines, Ethers

Alright lets work our way through number 7 starting with this challenging newman projection naming question that we are going to deconstruct here to make a little bit better for us we could build each of these and then use that model to depict the structure lets go through a way to do it without […]
