Phenol yog ntau soluble hauv NaOH dua hauv dej yog vim phenol yog me ntsis acidic. ua rau sodium phenoxide ruaj khov. los tsim ib Hydronium ion (H30). phenol nrog sodium yog cov tshuaj tiv thaiv qeeb vim phenol yog ib tug tsis muaj zog acid.
Ntawm no, vim li cas phenols tsawg soluble hauv dej?
Phenol kuj yog soluble nyob rau hauv dej mus rau qee qhov. Nws yog vim nws muaj peev xwm tsim hydrogen bonding nrog dej molecules. Txawm li cas los lub loj ib feem ntawm phenol molecule yog phenyl pawg uas tsis yog polar thiab li no nws solubility yog txwv nyob rau hauv dej.
Tsis tas li ntawd, vim li cas phenol soluble hauv dej ntau dua li benzene? Yog vim li cas rau tus nqi siab dua rau phenol yog inpart vim mus tas li dipole-dipole attractions vim theelectronegativity ntawm cov pa oxygen - tab sis feem ntau yog vim hydrogenbonding. Phenol yog nruab nrab soluble nyob rau hauv dej - txog 8 g phenol yuav yaj hauv 100 g ntawm dej.
Kuj tseem paub yog, hom tshuaj tiv thaiv dab tsi piav qhia txog kev solubility ntawm phenol hauv sodium hydroxide?
Txhua yam nyob rau hauv nruab nrab yuav qhia raws li ib co ntxoov ntxoo ntawm "nruj". Phenol reacts nrog sodium hydroxide tshuaj kom muab cov xim tsis muaj xim muaj sodium phenoxide. Hauv no tshuaj tiv thaiv , cov hydrogen ion tau raug tshem tawm los ntawm qhov yooj yim heev hydroxide ion hauv sodiumhydroxide daws.
Dab tsi cov ntsiab lus yog soluble hauv NaOH?
Dej Ethanol Methanol

Vim li cas 9 Fluorenone ntau dua polar dua fluorene?
Cov tshuab hnyav tau cais cov fluorene thiab 9-fluorenone raws li lawv qhov sib txawv ntawm cov qauv thiab polarity. Nyob rau hauv txoj cai, cov tshuaj compound uas ntws los ntawm kem ntawm ib tug ceev ceev yog ntau tsis-polar; Yog li ntawd, nyob rau hauv cov ntaub ntawv no fluorene yog ntau tsis-polar tshaj 9-fluorenone
Vim li cas S tsis muaj kev puas tsuaj ntau dua li P nthwv dej?
Lawv taug kev hauv tib txoj kev, tab sis lawv co hauv av rov qab thiab tawm mus perpendicular mus rau qhov kev taw qhia ntawm nthwv dej mus. S nthwv dej yog qhov txaus ntshai dua li P nthwv dej vim tias lawv muaj ntau dua amplitude thiab tsim kev txav ntsug thiab kab rov tav ntawm qhov av
Vim li cas NaOH soluble hauv dej?
Raws li qhov tshwm sim, daim ntawv cog lus polarity yuav siab heev rau NaOH vim muaj kev ua haujlwm polarization, ua rau NaOH polarsolute. Yog li ntawd, mus los ntawm lub hauv paus ntsiab lus- "Likedissolves nyiam", polar NaOH yuav yooj yim dissolve nyob rau hauv polar H2O. Li no NaOH yuav solublein dej ntau heev thiab lwm yam polar solvents zoo li ethanol
Vim li cas cov kab mob feem ntau tsim cov xeeb ntxwv ntau dua li muaj sia nyob?
Cov kab mob tsim cov xeeb ntxwv ntau dua li qhov muaj sia nyob. Cov kab mob tuaj yeem tuag los ntawm ntau yam ua rau: kab mob, kev tshaib plab, thiab noj, thiab lwm yam. Ib puag ncig tsis tuaj yeem txhawb nqa txhua yam kabmob uas yug los. Ntau tus tuag ua ntej lawv muaj peev xwm rov tsim dua
Yuav ua li cas muaj pes tsawg tus noob sib xyaw ua tau hauv gamete ntau lawm rau Dihybrid cross Vim li cas thiaj muaj ntau?
Muaj peev xwm gametes rau txhua tus niam txiv AaBb Txij li thaum txhua tus niam txiv muaj plaub qhov sib txawv ntawm cov alleles hauv gametes, muaj kaum rau kev sib txuas ua ke rau tus ntoo khaub lig no
