Raws li hydrocarbon ib feem ntawm ib cawv tau loj dua, cov cawv ua tsawg dua dej soluble thiab ntau soluble nyob rau hauv nonpolar kuab tshuaj. Phenol yog qee yam soluble hauv dej . Nws ua raws li cov kua qaub tsis muaj zog hauv dej , yog li kev daws teeb meem ntawm phenol yuav me ntsis acidic.

Ntawm no, vim li cas cawv thiab phenols yaj hauv dej?

(a) Cawv thiab Phenols yog soluble hauv dej vim lawv muaj peev xwm tsim oxygen bonds nrog dej molecules. (b) Cawv thiab Phenols yog soluble hauv dej vim lawv lub peev xwm los tsim cov ntawv cog lus hydrogen nrog dej molecules.

Ib sab saum toj no, puas yog phenols yaj hauv dej? Dej

Tsis tas li ntawd, cov cawv twg yog cov dej soluble tshaj plaws hauv dej?

Qhov feem ntau soluble yog tert- butanol (uas yog miscible hauv dej), ces 2- butanol tom qab ntawd 2-methyl- 1-propanol , thiab thaum kawg n-butanol . Ob yam tseem ceeb. Raws li cov saw ntev nce, solubility txo qis xws li methanol yog soluble ntau dua butanol . Ib feem ntawm cov pa roj carbon monoxide yog cov tsis muaj ncov qaumteb thiab zoo li tsis yaj hauv dej.

Vim li cas phenol tsis soluble hauv dej dua li ethanol?

Phenol yog thiab soluble hauv dej rau qee yam Nws yog vim nws lub peev xwm los tsim kev sib txuas nrog hydrogen dej molecules. Txawm li cas los xij qhov loj ntawm phenol molecule yog phenyl pawg uas tsis yog polar thiab li no nws solubility yog txwv nyob rau hauv dej . Txawm li cas los xij, qhov polarity ntawm qhov no kuj nce ntxiv hauv phenoxide ion.
