A pawg hydroxyl yog hydrogen bonded rau cov pa oxygen uas yog covalently bonded rau tag nrho cov molecule. Cawv yog subdivided los ntawm kev tshuaj xyuas cov pa roj carbon uas cov pawg hydroxyl ua ke. Yog tias cov pa roj carbon no txuas nrog rau lwm cov pa roj carbon atom, nws yog thawj (1o) cawv.

Tib neeg kuj nug, qhov sib txawv ntawm pawg hydroxyl thiab pawg cawv yog dab tsi?

Hydroxyl pawg yog ib tug functional pab pawg tam sim no hauv organic thiab inorganic tebchaw xws li cawv . Txawm li cas los xij, peb tseem siv lo lus no rau ob qho tib si pawg hydroxyl thiab hydroxyl radical. Lub ntsiab qhov sib txawv ntawm hydroxyl thiab cawv yog a hydroxyl yog ib tug functional pab pawg hos cawv yog ib qho organic compound.

pawg cawv hu ua dab tsi? Cawv yog homologous series nyob rau hauv uas cov tebchaw muaj ib tug haumxeeb pawg hu ua cov hydroxyl pab pawg (-OH). General molecular formula rau cawv yog C H2 ib n+1OH. Cawv yog tag nrho cov derivatives ntawm hydrocarbons uas ib los yog ntau tshaj ntawm cov hydrogen atoms nyob rau hauv cov hydrocarbon tau hloov los ntawm ib tug hydroxyl pab pawg.

Cov lus nug tseem yog, puas yog ib pawg hydroxyl?

Hydroxyl pawg yog ib tug functional pab pawg pom nyob rau hauv qab zib thiab cawv. A pawg hydroxyl muaj ib qho hydrogen thiab ib qho oxygen atom thiab tuaj yeem sau ua ib qho - OH lub HO-. Hydroxyl pawg yog polar, thiab sab oxygen yog ib txwm tsis zoo, thaum lub hydrogen sab yog ib txwm zoo.

Lub ntsiab lus ntawm hydroxyl pawg yog dab tsi?

Hydroxyl Group txhais hauv Chemistry Anne Marie Helmenstine, Ph pawg hydroxyl yog ib tug functional pab pawg muaj ib tug hydrogen atom covalently bonded rau ib tug oxygen atom. Cov pawg hydroxyl yog qhia los ntawm -OH hauv cov qauv tshuaj thiab muaj tus nqi valence ntawm -1.
