Ob moles ntawm sodium reacts nrog chlorobenzenenyob rau hauv muaj ether thiab daim ntawv biphenyl. Cov tshuaj tiv thaiv rau kev tsim ntawm biphenyl los ntawm chloro benzene yog raws li nram no: (ii) Propene rau 1-iodopropane: Peb paub tias Propene reacts nrog diborane thiab hydrogen peroxide nyob rau hauv muaj sodium hydroxide thiab daim ntawv propan -1-ol.
Qhov twg ntawm cov tshuaj tiv thaiv hauv qab no tuaj yeem hloov chlorobenzene rau biphenyl?
Teb: Chlorobenzene hloov mus rau biphenyl los ntawm kev siv Fittig cov tshuaj tiv thaiv. Chlorobenzene reacts nrog sodium nyob rau hauv muaj ether los ua biphenyl.
Koj hloov chlorobenzene rau toluene li cas?
Teb: Kev xaiv (i) Wurtz Fittig cov tshuaj tiv thaivtuaj yeem siv los hloov Chlorobenzene rau toluene los ntawm kev ua rau nws hnov mob rau sodium nyob rau hauv muaj methyl chloride yuav muab rau koj toluene. Cov tshuaj tiv thaiv no tseem muab cov khoom lag luam intramolecular li ethane pom raws li cov khoom lag luam.
Koj hloov chlorobenzene rau aniline li cas?
Qhov kev xaiv zoo tshaj plaws yog tau los ntawm kev siv siab molar ratio ntawm ammonia piv rau chlorobenzene. Lub benzene yog reacted nrog sulfuric acid thiab nitric acid los tsim nitrobenzene uas yog ntxiv kho nrog HCl nyob rau hauv lub xub ntiag ntawm catalyst tin thiab cov khoom tau txais yog aniline.
Koj ua li cas hloov cov chlorobenzene hauv qab no rau 2 chlorotoluene?
Thaum chlorobenzene rhuab nrog chloromethane nyob rau hauv lub xub ntiag ntawm anhydrous aluminium chloride , nws tau hloov mus ua 2-chlorotolune.
… Cov mis mos molecular ntawm cov tebchaw koom nrog hauv cov tshuaj tiv thaiv yog raws li hauv qab no:
- YChlorobenzene -
- Aluminium chloride -
- 2-Chlorotoluene -

Yuav siv sijhawm ntev npaum li cas rau cov pob txha pob txha hloov mus rau engraft?
Engraftment yog thaum hloov cov qia hlwb nkag mus rau hauv cov ntshav, ua rau lawv txoj hauv kev mus rau cov pob txha thiab pib ua cov qe ntshav tshiab. Nws feem ntau yuav siv sij hawm kwv yees li 2 txog 6 lub lis piam kom pib pom qhov rov qab mus rau qhov qub cov ntshav suav .
Puas yog qhov hloov pauv hloov tau tuaj yeem hloov kho?
Qhov kev ywj pheej (lossis tswj hwm) qhov sib txawv yog qee yam uas tus kws sim lub hom phiaj hloov pauv lossis txawv ntawm qhov kev tshawb nrhiav. Qhov dependent (los yog teb) sib txawv yog ib qho uas tau pom thiab yuav hloov pauv hauv cov lus teb rauqhov sib txawv ntawm tus kheej .
Puas hloov pauv hloov pauv tuaj yeem hloov kho?
Nyob hauv ntau qhov kev sim, qhov sib txawv ntawm kev ywj pheej yog kev tsim kho uas tsuas yog tuaj yeem tswj tsis ncaj . Puas yog qhov sib txawv nyob ntawm qhov ntsuas lossis tswj tau? Ib qhov sib txawv yog qhov ntsuas lossis manipulated hauv kev sim.
Chlorobenzene tsw zoo li cas?
Chlorobenzene yog cov kua txiv neej ua tsis muaj xim uas kub hnyiab tau sai. Nws muaj ib tug zoo nkauj tsw zoo li tus ntxhiab tsw ntawm almonds. Qee qhov ntawm nws yuav yaj hauv dej. Nws kuj hloov mus ua vapor thiab mus rau saum huab cua . Puas yog chlorobenzene lom rau tib neeg?
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau?
Ntau tus neeg ua tiav lawv txoj kev kho hniav thiab muaj cov hniav zoo nkauj, txawm li cas los xij, thaum lawv luag ntxhi lawv pom cov hniav luv luv lossis cov pos hniav ntau dhau "gummy luag". Cosmetic crown lengthening yog ib txoj hauv kev yooj yim uas tuaj yeem ua tau zoo heev ua kom lub ntsej muag luag ntxhi ntawm cov neeg mob no .
