Functional Groups in Organic Compounds
Functional Groups in Organic Compounds
Check us out at www.tutorvista.com In organic chemistry, functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. The same functional group will undergo the same or similar chemical reaction(s) regardless of the size of the molecule it is a part of. However, its relative reactivity can be modified by nearby functional groups. The word moiety is often used synonymously to "functional group," but, according to the IUPAC definition, a moiety is a part of a molecule that may include functional groups as substructures. For example, an ester is divided into an alcohol moiety and an acyl moiety, but has an ester functional group. Also, it may be divided into carboxylate and alkyl moieties. Combining the names of functional groups with the names of the parent alkanes generates a powerful systematic nomenclature for naming organic compounds. The atoms of functional groups are linked to each other and to the rest of the molecule by covalent bonds. When the group of atoms is associated with the rest of the molecule primarily by ionic forces, the group is referred to more properly as a polyatomic ion or complex ion. And all of these are called radicals, by a meaning of the term radical that predates the free radical. The first carbon atom after the carbon that attaches to the functional group is called the alpha carbon; the second, beta carbon, the third, gamma carbon, etc. If there is another <b>...</b>

Ester (The Queenly Functional Group)
Ester (The Queenly Functional Group)
Script Included (bonus hints for Fischer Esterification at end) This is an ester. Now you could memorize it the boring way, or you could remember the story of Esther. Once you know the characters, you can always identify this functional group! The star of our show is a beautiful young woman whose name, Hadassah or Esther, means star. She was a commoner (C can stand for Commoner and Carbon), but shes going to be queen. She is going to be queen because the king of Persia sent a proclamation that he was replacing his queen, and all the young women in the kingdom, including our star, had to go to the palace for a giant "picking ceremony." They got all dressed up (That C also looks like a fancy bracelet and it is right next to the O which reminds me of a crown). Our lovely commoner pleased the king. He gave her perfumes and nice smelling resins and a place in the palace. Finally, he made her his queen. The single bond between the commoner and the crown is marriage. The R group bonded to the C is our new queens cousin, Mordecai. He took care of her and advised her after her parents died. You could think R for Relative, or R for advisoRRR. It doesnt really matter what Mordecai looks like. Any R group will do. The king has his own advisor, Haman, which we can call R group prime (R'). Once again, any R group will do. But Im pretty sure Haman would like his R group to be prime while Mordecais is regular, since thats just the sort of man he was. Theres another king in the story <b>...</b>

16. Recognizing Functional Groups
16. Recognizing Functional Groups
Freshman Organic Chemistry (CHEM 125) This lecture continues the discussion of the HOMO/LUMO view of chemical reactivity by focusing on ways of recognizing whether a particular HOMO should be unusually high in energy (basic), or a particular LUMO should be unusually low (acidic). The approach is illustrated with BH_3, which is both acidic and basic and thus dimerizes by forming unusual "Y" bonds. The low LUMOs that make both HF and CH_3F acidic are analyzed and compared underlining the distinction between MO nodes that derive from atomic orbitals nodes (AON) and those that are antibonding (ABN). Reaction of HF as an acid with OH- is shown to involve simultaneous bond-making and bond-breaking. 00:00 - Chapter 1. Why So High, Why So Low?

Mechanism for the cyclic formation of acetal/ketal groups from aldehydes/ketones and diols
Mechanism for the cyclic formation of acetal/ketal groups from aldehydes/ketones and diols
Animation of the mechanism for the formation of acetal/ketal functional groups from aldehydes/ketones and diols (functional group interconversion). Although acid is represented as H+, in this animation, in "reality" it is actually H3O+ (ie a protonated water molecule). Reaction conditions: Benzene is used as a solvent. p-toluenesulfonic acid is used as the acid catalyst. The reaction is forced towards the acetal/ketal products using heat and by the removal of water via reflux using a Dean-Stark condenser. Acetal/ketal functional groups are useful as protecting groups since the change in reactivity, from an aldehyde/ketone to an acetal/ketal, can prevent the protected ketone/aldehyde from reacting with certain reagents. For example ketones will react with Grignard reagents while ketals do not since ketals lack a carbonyl functional group (C=O bond). Acetals/ketals are stable under basic and neutral conditions as well as to most reducing and oxidising agents. But can be removed/are unstable under acid catalysed hydrolysis. Have I made a mistake? Got a suggestion on how I could improve? Let me know!
