Txawm li cas los xij, acetone tseem suav tias yog a polarprotic kuab tshuaj , txawm tias qhov tseeb tias nws yog acidic, thiab tsis muaj acidic tsawg dua li cawv. Ces dua, acetone (thiab lwm yam carbonyl muaj cov kuab tshuaj ) yog, qhov tseeb, pluag cov kuab tshuaj Thaum siv cov hauv paus muaj zog vim lawv cov acidity siab.

Ib yam li ntawd, nws raug nug, yam tshuaj hnyav npaum li cas yog acetone?

Acetone , los yog propanone, yog cov organic compound nrog cov mis (CH3)2CO. Nws yog cov kua tsis muaj xim, tsis muaj zog, flammable thiab yog qhov yooj yim thiab tsawg tshaj plaws ketone. Acetone yog miscible nrog dej thiab ua haujlwm tseem ceeb kuab tshuaj nyob rau hauv nws tus kheej txoj cai, feem ntau yog rau tu lub hom phiaj inlaboratories.

Ib sab saum toj, puas yog acetone heev polar? Acetone yog a polar molecule vim nws hasa polar daim ntawv cog lus, thiab cov qauv molecular tsis ua rau lub dipole raug tshem tawm. C yog me ntsis electronegative dua H(2.4 vs. 2.1).

Yog li ntawd, THF puas yog polar aprotic hnyav?

Hydrophilic GO yog tsis zoo exfoliated nyob rau hauv nonnaqueous cov kuab tshuaj , np., polar aprotic kuab tshuaj xws li N, N-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), thiab tetrahydrofuran tshuaj ( THF ).

Puas yog cawv yog cov kuab tshuaj polar?

Feem ntau, pawg hydroxyl ua cawv polar . Cov pab pawg no tuaj yeem tsim cov ntawv cog lus hydrogen rau ib leeg thiab rau feem ntau lwm cov tebchaw. Nrog rau lub xub ntiag ntawm lub polar OH cawv yog dej-soluble ntau dua li cov hydrocarbons yooj yim. Methanol, ethanol , thiab propanol yog misciblein dej.
