Cyanohydrins muaj cov qauv qauv ntawm R2C(OH) CN. Tus "R" ntawm tus qauv qhia txog alkyl, aryl, lossis hydrogen. Txhawm rau tsim cov cyanohydrin, hydrogen cyanide ntxiv reversibly rau carbonyl pawg ntawm cov organic. compound yog li tsim ib hydroxyalkanenitrile adducts (feem ntau paub thiab hu ua cyanohydrins).

Ib yam li ntawd, Cyanohydrin molecule yog dab tsi?

A tshuaj cyanohydrin yog ib qho organic compound uas muaj ob qho tib si cyanide thiab hydroxy pawg ntawm aliphatic seem ntawm lub molecule . Vim Cyanohydrins feem ntau yog siv los ua cov tshuaj intermediates, cov ntaub ntawv ntawm kev tsim khoom thiab cov nqi feem ntau tsis tau luam tawm.

Ib tug kuj yuav nug, yuav ua li cas tshwm sim thaum acetaldehyde reacts nrog HCN? Thaum twg acetaldehyde teb nrog HCN , cyanohydrin (CH3CH (OH) CN) yuav tsim thiab thaum qhov no raug rau acid hydrolysis ib alpha hydroxy acid (CH3CH (OH) COOH) los yog alpha-beta unsaturated acid (CH2 = CH (OH) COOH) yuav tsim.

Ib yam li ntawd, Cyanohydrin tsim yog dab tsi?

A tshuaj cyanohydrin Cov tshuaj tiv thaiv yog cov tshuaj lom neeg cov tshuaj tiv thaiv los ntawm aldehyde lossis ketone nrog cyanide anion lossis nitrile los tsim tshuaj cyanohydrin . Qhov sib ntxiv ntawm nucleophilic no yog cov tshuaj tiv thaiv rov qab tab sis nrog aliphatic carbonyl compounds equilibrium yog nyob rau hauv kev pom zoo ntawm cov tshuaj tiv thaiv.

Semicarbazone txhais li cas?

Hauv organic chemistry, a semicarbazone yog ib tug derivative ntawm imines tsim los ntawm ib tug condensation cov tshuaj tiv thaiv ntawm ib tug ketone los yog aldehyde thiab semicarbazide.
