The New York Times noted there is a racial dynamic to many reaction videos which involve younger, Black listeners responding positively to music by older, white musicians. [9] [10] Some YouTube channels doing music reaction videos have become very successful, with major music labels reaching out to channels to promote their artists. [8]
Acylium ions are intermediates in several reactions, such as the Friedel-Crafts acylation of arenes by acetyl chloride in the presence of aluminium trichloride: C 6 H 5 R + CH 3 CO + + AlCl − 4 → CH 3 COC 6 H 4 R + HCl + AlCl 3. Such depictions may be simplistic because of ion-pairing between the acetyl cation (an acylium cation) and the ...
Cations are positively (+) charged ions while anions are negatively (−) charged. This can be remembered with the help of the following mnemonics. Cats have paws ⇔ Cations are pawsitive. [27] Ca+ion: The letter t in cation looks like a + (plus) sign. [28] An anion is a negative ion. (An egative ion ⇒ Anion). [29]
If it is the result of a reaction between a strong acid and a strong base, the result is a neutral salt. Weak acids reacted with weak bases can produce ionic compounds with both the conjugate base ion and conjugate acid ion, such as ammonium acetate. Some ions are classed as amphoteric, being able to react with either an acid or a base. [59]
In polymer chemistry, ionic polymerization is a chain-growth polymerization in which active centers are ions or ion pairs. [2] It can be considered as an alternative to radical polymerization, and may refer to anionic polymerization or cationic polymerization. [3] As with radical polymerization, reactions are initiated by a reactive compound.
Iminium cations are reduced to the amines, e.g. by sodium cyanoborohydride. Iminium cations are intermediates in the reductive amination of ketones and aldehydes. Unsymmetrical iminium cations undergo cis-trans isomerization. The isomerization is catalyzed by nucleophiles, which add to the unsaturated carbon, breaking the C=N double bond. [3]
The dihydrogen cation or hydrogen molecular ion is a cation (positive ion) with formula +. It consists of two hydrogen nuclei ( protons ), each sharing a single electron . It is the simplest molecular ion .
In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] of a series of metals, arranged by their "reactivity" from highest to lowest.
