Hydroxyl pawg (-OH), pom nyob rau hauv cawv, yog polar thiab yog li ntawd hydrophilic (dej nyiam) tab sis lawv cov pa roj carbon monoxide yog tsis-polar uas ua rau lawv hydrophobic . Cov molecule nce zuj zus tag nrho cov tsis muaj polar thiab yog li ntawd tsawg soluble nyob rau hauv lub polar dej raws li cov carbon saw ntev.

Kuj nug, pab pawg twg ua haujlwm yog hydrophilic?

pawg carboxyl

Qhov thib ob, cov pab pawg ua haujlwm puas yog hydrophilic lossis hydrophobic? Cov pab pawg ua haujlwm tuaj yeem muab faib ua hydrophobic los yog hydrophilic Raws li lawv cov nqi thiab polarity yam ntxwv. Lub xwb pawg hydrophobic Hauv qab no yog methyl (CH 3?start subscript, 3, kawg subscript) pab pawg , uas yog nonpolar.

Ntxiv mus, puas yog hydroxyl pawg polar?

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 -OH lossis HO-. Hydroxyl pawg yog polar , thiab cov pa oxygen ib txwm tsis zoo, thaum lub hydrogen sab ib txwm zoo.

Puas yog hydroxyl pawg acidic?

Tsis- kua qaub Muaj nuj nqi Pawg Feem ntau ua haujlwm pab pawg muaj me ntsis los tsis cuam tshuam rau acidity ntawm molecule. Cov hydroxyl , uas yog ib qho yooj yim OH txuas rau lub molecule, tuaj yeem xav poob nws cov hydrogen, ua rau nws kua qaub , tab sis qhov ntawd tsis yog li cas cov molecule feem ntau cuam tshuam.
