Qhov sib txawv ntawm isopropyl thiabisoPropanollus dag hauv lawv cov qauv molecular thiab cov khoom. Thaum ob leeg ntawm lawv muaj tib cov pa roj carbon thiab hydrogen atoms, lawv cov qauv tshuaj sib txawv, ua rau muaj kev sib txawv ntawm lawv lub cev thiab tshuaj lom neeg.

Isopropyl haus cawv, tseem hu ua isopropanol, belongs rau tsev neeg ntawm cov cawv thiab muaj cov tshuaj noj ch3-ch (oh) -ch3. Nws yog qhov tsis sib xws, cov kua tsis muaj kob uas muaj cov yam ntxwv tsw ntxhiab. Nws polarity thiab kev ua haujlwm nrog dej ua rau nws muaj cov ntawv thov kev lag luam tseem ceeb hauv ntau thaj teb xws li cov kuab tshuaj, cov tshuaj tiv thaiv kab mob, thiab tshuaj ntxuav kom huv. IsoPropanol tseem siv los ua cov khoom siv raw rau kev tsim cov tshuaj lom neeg.

Ntawm qhov tod tes, isopropyl sawv cev rau cov hydrocarbon radical (c3h7-), uas yog ib qho alkyl derivative ntawm cov khoom siv (C3H8). Nws yog ib qho isomer ntawm Butane (C4h10) thiab tseem hu ua kev tab sis Tertiary. Isopropyl cawv, ntawm qhov tod tes, yog haus cawv ntawm isopropyl. Thaum iSopropyl cawv muaj hydroxyl (-oh) pab pawg txuas rau nws, isopropyl tsis muaj ib pab pawg hydroxyl. Qhov kev sib txawv no ntawm ob qhov ua rau muaj qhov sib txawv tseem ceeb hauv lawv lub cev thiab tshuaj lom neeg.

Isopropyl cawv yog mistible nrog dej vim tias nws cov ncov qaumteb qab zib, hos isropropyl yog tsis yog dej hauv dej. Cov pab pawg hydroxyl tam sim no hauv isopropanol ua rau nws rov qab ua ntau dua thiab polar dua isopropyl. Qhov no polarity txawv cuam tshuam rau lawv solubility thiab mis nyuj nrog lwm cov tebchaw.

Hauv kev xaus, thaum oopropyl thiab isopropanol muaj tib cov pa roj carbon thiab hydrogen atoms, lawv cov qauv tshuaj txawv txawv. Lub xub ntiag ntawm cov pab pawg hydroxyl hauv isopropanol muab nws tus cim polar, ua rau nws tsis muaj dej. Isopropyl, tsis muaj pawg hydroxyl, tsis muaj cov cuab yeej no. Yog li ntawd, thaum isopropanol nrhiav tau ntau daim ntawv thov muaj, isopropyl kev siv tau txwv.
