Alcohols is

soluble in water. Qhov no yog vim pawg hydroxyl hauv cawv uas tuaj yeem tsim cov hydrogen bons nrog dej molecules. Cawv nrog ib tug me me hydrocarbon saw yog soluble heev. Raws li qhov ntev ntawm cov saw hlau hydrocarbon nce, cov solubility hauv dej txo.

Yuav ua li cas thiaj li solubility ntawm cawv hauv dej?

Vim cawv tsim hydrogen bonds nrog dej, lawv zoo li soluble hauv dej. Cov pab pawg hydroxyl hu ua hydrophilic ("dej-hlub") pab pawg, vim tias nws tsim hydrogen bonds nrog dej thiab txhim kho cov solubility ntawm cawv hauv dej.

Yuav ua li cas cuam tshuam rau kev solubility ntawm cawv?

Tus naj npawb ntawm cov pa roj carbon atoms hauv cawv cuam tshuam nws cov solubility hauv dej, raws li qhia hauv Table 13.3. Raws li qhov ntev ntawm cov saw hlau txuas ntxiv, cov polar OH pawg ua ib feem me me ntawm cov molecule, thiab cov molecule ua zoo li hydrocarbon. Lub solubility ntawm cawv txo qis sib xws.

Vim li cas cov kua dej cawv nce ntxiv nrog cov ceg?

Alcohols: Cawv yog soluble nyob rau hauv dej vim lawv tsim intermolecular hydrogen bonding nrog dej molecules. … Lub solubility ntawm isomeric alcohols nce nrog branching vim thaj tsam ntawm hydrocarbon ib feem txo nrog branching.

Vim li cas alkanesSoluble hauv cawv?

Alkanes tsis yog polar thiab yog li cuam tshuam tsuas yog los ntawm cov tsis muaj zog dispersion zog. Alkanes nrog ib mus rau plaub carbon atoms yog gases ntawm chav tsev kub. … Yog li, hos cov hydrocarbons yog insoluble nyob rau hauv dej, cawv nrog ib mus rau peb carbon atoms yog soluble tag nrho.
