Aldehydes teb nrog sodium bisulphite (sodium hydrogen sulphite) muab cov khoom ntxiv. Ketones, tshwj tsis yog rau methyl ketones, tsis hnov mob nrog sodium bisulphite vim yog steric hinderance (neeg coob coob).
Uas tsis hnov mob nrog sodium bisulphite?
Hauv kev xaiv (C) C6H5CHO yog ib qho aldehyde. … Cov aldehydes no ua raws li qhov xwm txheej yog li nws tab tom tsim cov tshuaj sodium bisulphite. Yog li ntawd, the C6H5COCH3 tsis tsim sodium bisulfite ntxiv cov khoom nrog sodium bisulphite tov vim tias cov no tsis ua raws li tus mob & tsis hnov mob nrog sodium bisulphite.
Puas sodium react nrog aldehydes?
Nyob rau hauv kev txo qis bimolecular, coj los ntawm cov hlau nquag xws li sodium (Na) lossis magnesium (Mg), ob lub molecules ntawm ib qho aldehyde ua ke muab (tom qab hydrolysis) a compound nrog -OH pawg ntawm cov pa roj carbon uas nyob ib sab; e.g., 2RCHO → RCH(OH)CH(OH)R. Cov tshuaj tiv thaiv oxidation ntawm aldehydes yog qhov tseem ceeb tsawg dua li kev txo qis.
Puas aldehydes hnov mob nrog sodium hydrogen carbonate?
Aldehydes thiab ketones tsis yog acidic thiab
yuav tsis hnov mob nrog sodium bicarbonate.
aldehydes ua li cas nrog?
Aldehydes thiab ketones teb nrog primary amines los ua ib pawg ntawm cov tshuaj hu ua imines. Cov txheej txheem rau kev tsim imine yog ua los ntawm cov kauj ruam hauv qab no: 1. Ib khub tsis sib koom ntawm electrons ntawm nitrogen ntawm amine.yog attracted rau ib nrab-zoo carbon ntawm pawg carbonyl.
