A functional group is a specific group of atoms that helps determine the chemistry and reactivity of the overall molecule. When classifying functional groups, we look at both the specific atoms present, as well as the manner in which they are connected to each other. While there are an overwh...
Organic Functional Groups: Aldehydes, ketones, 1° alcohols, etc. Organic chemistry is dominated by the "functional group approach", where organic molecules are deemed to be constructed from: An inert hydrocarbon skeleton onto which functional groups (FGs) are attached or superimposed....
For example, depending on how functional groups are placed, the mechanisms of accumulation, and the persistence and fate of organic compounds in the soil are determined. The hydroxyl functional groups (shown in Table 6.2) that exist in water consist of a hydrogen atom and an oxygen atom bonded...

ChemistDice is a game of cards and a die developed for first-year general chemistry students to learn the nomenclature of organic compounds and the major functional groups. The game enables students to review organic compound nomenclature, such as amines, alcohols, alkyl halides, alkyne, alkenes,...
The Main-Group Chemistry Database MGCDB84 database, compiled by Mardirossian and Head-Gordon5“from the benchmarking activities of numerous groups, including Hobza, Sherrill, Truhlar, Herbert, Grimme, Karton, and Martin”. It comprises 84 data sets containing 4,986 data for NC interactions, IEs...
Likewise, others studies examined 5 groups of fresh carrots and found that the β-carotene and vitamin A contents were 12,300 µg/100 g and 2,054.1 RE/100 g, respectively (Aremu and Nweze, 2017). Table 2. Phytochemical components (on a dry basis) of carrot root powder1 Sample...
