CH3CH 2 OH , hu ua ethanol, yog ib qho cawv uas muaj cov saw luv luv hydrophobic thiab pab pawg hydrophilic. Cawv muaj peev xwm yaj nyob rau hauv dej vim yog pawg cawv ntawm qhov kawg, tab sis raws li cov saw hlau carbon loj hlob ntev dua los yog loj dua (vim yog branching), solubility txo.

Yog li, yog ch3ch2oh soluble hauv dej?

Soluble : CH3CH 2 OH yog polar uas tuaj yeem tsim hydrogen bonding attraction nrog O-H diploes hauv dej uas yog ntau polar molecule.

Tsis tas li ntawd, puas yog ch3 ch2 5oh soluble hauv dej? Nqe lus piav qhia: 1-Hexanol yog cov organic cawv nrog rau 6 carbon saw thiab condensed qauv qauv ntawm CH3 (CH2) 5OH. Cov kua tsis muaj xim no yog me ntsis soluble hauv dej, tab sis miscible nrog ether thiab ethanol.

Kuj paub yog, uas yog ntau dua soluble hauv dej ch3ch2oh lossis ch3ch3?

TXC 3CH 3 yog nonpolar thiab yog ib qho yooj yim molecule. CH3CH2CH3 thiab CH3CH 2 OH muaj qee qhov zoo sib xws hauv qhov loj thiab qhov nyuaj, tab sis CH3CH2CH3 yog nonpolar thaum CH3CH 2 OH yog polar nrog hydrogen bonding. Yog li ntawd CH3CH 2 OH muaj zog tshaj plaws. Polar molecules yog soluble nyob rau hauv dej , nonpolar molecules tsis yog.

Yuav ua li cas thaum ethanol yaj hauv dej?

Thaum twg ethanol dissolves nyob rau hauv dej , cov ethanol molecules nyob twj ywm tab sis tsim tshiab hydrogen bonds nrog rau dej . Thaum, txawm li cas los xij, ib qho ionic compound xws li sodium chloride (NaCl) dissolves nyob rau hauv dej , sodium chloride lattice dissociates rau hauv nyias ions uas yog solvated (qhwv) nrog ib txheej ntawm dej molecules.
