Racemic \Ra*ce"mic\ (r[.a]*s[=e]"m[i^]k), a. [Cf. F.
rac['e]mique. See {Raceme}.] (Chem.)
Pertaining to, or designating, an acid found in many kinds of
grapes. It is also obtained from tartaric acid, with which it
is isomeric, and from sugar, gum, etc., by oxidation. It is a
sour white crystalline substance, consisting of a combination
of dextrorotatory and levorotatory tartaric acids. --Gregory.
[1913 Webster]

  • Racemic mixture - Wikipedia
    Racemic mixture In chemistry, a racemic mixture or racemate ( reɪˈsiːmeɪt, rə -, ˈræsɪmeɪt [1]) is a mixture that has equal amounts (50:50) of left- and right-handed enantiomers of a chiral molecule or salt Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates
  • What Is a Racemic Mixture? – Master Organic Chemistry
    A "racemic mixture" is an equal mixture of two enantiomers - like 100 left shoes and 100 right shoes, or an equal collection of left right gloves
  • RACEMIC Definition Meaning - Merriam-Webster
    The meaning of RACEMIC is of, relating to, or constituting a compound or mixture that is composed of equal amounts of dextrorotatory and levorotatory forms of the same compound and is not optically active
  • Racemic mixture | Definition, Example, Facts | Britannica
    Racemic mixture, a mixture of equal quantities of two enantiomers, or substances that have dissymmetric molecular structures that are mirror images of one another The name is derived from racemic acid, the first such substance to be carefully studied
  • Racemic Mixtures - Chemistry Steps
    A mixture containing equal amounts of two enantiomers is called a racemic mixture or a racemate Racemic mixtures are optically inactive and therefore they are achiral
  • Racemic Mixtures - ChemTalk
    A racemic mixture or racemate is a mixture that contains an equal amount of two enantiomers Racemic mixtures are optically inactive
  • 5. 8: Racemic Mixtures and the Resolution of Enantiomers
    Study Notes A racemic mixture is a 50:50 mixture of two enantiomers Because they are mirror images, each enantiomer rotates plane-polarized light in an equal but opposite direction and is optically inactive If the enantiomers are separated, the mixture is said to have been resolved A common experiment in the laboratory component of introductory organic chemistry involves the resolution of a
  • Racemic Definition in Organic Chemistry: A Detailed Explanation . . .
    🔍 TL;DR: A **racemic mixture** (or racemate) is an equimolar blend of two **enantiomers**—mirror-image molecules with identical physical properties but opposite optical rotations These mixtures are **chiral**, meaning they interact differently with other chiral compounds (like biological systems) Understanding racemics is crucial in organic chemistry, drug development, and natural
  • What Is a Racemic Mixture? Definition and Examples
    A racemic mixture is a specific chemical blend that highlights this molecular phenomenon, representing a unique state of these mirror-image molecules, known as enantiomers, in equal proportion
  • Racemic mixture - Wikiwand
    In chemistry, a racemic mixture or racemate ( reɪˈsiːmeɪt, rə -, ˈræsɪmeɪt [1]) is a mixture that has equal amounts (50:50) of left- and right-handed enantiomers of a chiral molecule or salt Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates
