Substituent Effects on Acidity of Carboxylic Acids01:31

Substituent Effects on Acidity of Carboxylic Acids

6.6K
The acidity of carboxylic acids is influenced by the nature of the substituents bounded to the functional group. The acid strength is determined by the stability of the carboxylate anion—the conjugate base formed by dissociating the corresponding carboxylic acid.

Acetals and Thioacetals as Protecting Groups for Aldehydes and Ketones01:24

Acetals and Thioacetals as Protecting Groups for Aldehydes and Ketones

4.1K
Acetals are formed by reacting two equivalents of alcohol with carbonyl compounds like aldehydes or ketones. Acetals are unaffected by bases, nucleophiles, oxidizing agents, and reducing agents. They serve as protecting groups for aldehydes and ketones. Acetals can be easily formed and also easily removed via mild acid hydrolysis.
In the presence of multiple functional groups, when selective reduction of one group over the other is desired, groups like aldehydes and ketones that form acetals...

Acid Halides to Esters: Alcoholysis01:12

Acid Halides to Esters: Alcoholysis

2.8K
Alcoholysis is a nucleophilic acyl substitution reaction in which an alcohol functions as a nucleophile. Acid halides react with alcohol to produce esters. The mechanism proceeds in three steps:

Polyprotic Acids03:38

Polyprotic Acids

29.1K
Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

Preparation of Diols and Pinacol Rearrangement01:57

Preparation of Diols and Pinacol Rearrangement

3.4K
Compounds bearing two hydroxyl groups are known as diols. When the hydroxyl groups are located on adjacent carbon atoms, the diols are called vicinal diols or glycols. Under acidic conditions, vicinal diols undergo a specific reaction called pinacol rearrangement.
The reaction begins with transferring a proton from the acid catalyst to one of the hydroxyl groups, producing an oxonium ion.

IUPAC Nomenclature of Carboxylic Acids01:16

IUPAC Nomenclature of Carboxylic Acids

9.2K
IUPAC names of carboxylic acids are systematically derived following a few rules discussed below.
For acyclic saturated monocarboxylic acids, the longest hydrocarbon chain containing the –COOH carbon is identified as the parent chain. Then, the last -e of the parent hydrocarbon name is replaced with a suffix -oic acid.

Area of Science:

  • Phonetics
  • Linguistics
  • Speech Science

Background:

  • The extended International Phonetic Association (extIPA) chart is a crucial tool for phonetic transcription.
  • Previous versions of the chart may contain diacritics that require refinement for clarity and accuracy.

Purpose of the Study:

  • To document specific changes made to three diacritics on the extIPA chart.
  • To present a comprehensively updated extIPA chart incorporating these modifications.

Main Methods:

  • Review and analysis of existing extIPA diacritics.
  • Implementation of revised diacritic forms.
  • Compilation of the complete, updated extIPA chart.

Main Results:

  • Three specific diacritics on the extIPA chart have been modified.
  • A new, updated version of the entire extIPA chart is now available.

Conclusions:

  • The updated extIPA chart reflects improvements in phonetic transcription accuracy.
  • This revised chart will benefit researchers and practitioners in phonetics and speech sciences.
