  4. Chirality (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Chirality_(chemistry)

    A chiral substance is enantiopure when only one of two possible enantiomers is present so that all molecules within a sample have the same chirality sense. Use of homochiral as a synonym is strongly discouraged. [22] A chiral substance is enantioenriched or heterochiral when its enantiomeric ratio is greater than 50:50 but less than 100:0. [23]

    en.wikipedia.org/wiki/Bromoform

    Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.

    en.wikipedia.org/wiki/Absolute_configuration

    COOH, R, NH 2 and H (where R is the side-chain) are arranged around the chiral center carbon atom. With the hydrogen atom away from the viewer, if the arrangement of the CO→R→N groups around the carbon atom as center is counter-clockwise, then it is the L form. [14] If the arrangement is clockwise, it is the D form. As usual, if the ...

  9. 1-Bromo-3-chloropropane - Wikipedia

    en.wikipedia.org/wiki/1-Bromo-3-chloropropane

    1-Bromo-3-chloropropane is an organohalogen compound with the formula Br(CH 2) 3 Cl. It is a colorless liquid, produced by free-radical addition of hydrogen bromide to allyl chloride. [1] It is used as an alkylating agent to install the –(CH 2) 3 Cl [2] [3] and –(CH 2) 3 – groups. [4] For example, it is a precursor to 4-chlorobutyronitrile.
