p-Nitrophenol muaj cov tshuaj sib xyaw ua ke hydrogen yog li nws muaj qhov kub hnyiab ntau dua thiab tsis muaj zog dua li o-nitrophenol uas muaj intramolecular hydrogen bonding.
Qhov twg muaj qhov kub siab dua ntawm o-nitrophenol lossis p-nitrophenol?
P-nitrophenol muaj qhov sib xyaw ua ke hydrogen. Intermolecular hydrogen bonding ua rau lub koom haum molecular. Qhov no tsub kom lub boiling point. Yog li, O-nitrophenol muaj qhov kub siab qis dua P-nitrophenol.
Vim li cas Ortho nitrophenol muaj qhov kub hnyiab ntau dua?
P-nitrophenol qhia intermolecular hydrogen bonding. Yog li nws muaj qhov sib txuas ntau dua. Whereas o-nitrophenol qhia intra molecular H-bonding li no qis boiling point.
Vim li cas p-nitrophenol muaj cov ntsiab lus melting siab dua o-nitrophenol?
Nyob rau hauv p-nitrophenol, lub koom haum molecular tshwm sim vim muaj kev sib txuas ntawm hydrogen ntau ntawm cov molecules (intermolecular hydrogen bonding). Yog li ntawd, nws muaj ntau dua melting thiab boiling ntsiab lus. Hauv o-nitrophenol, txij li OH thiab NO2 nyob ze rau ib leeg, intramolecular hydrogen bonding yuav siv qhov chaw.
Vim li cas 4 Nitrophenol muaj qhov kub siab dua?
siab dua qhov vapor siab ntawm cov kua ntawm qhov ntsuas kub, siab dua qhov volatility thiab txo qhov kub ntawm cov kua. Yog li nyob rau hauv cov ntaub ntawv ntawm 4-nitrophenol, nws qhov hnyav molecular nce ua rau nws tsis hloov pauvuas ua rau nws qhov kub hnyiab.

Qhov no yog vim qhov ntsuas kub ntawm qhov ntsuas kub, tsis yog lub siab ntawm dej. … Thaum cov dej siab tshaj qhov ntsuas kub siab tshaj plaws, lub ntsiab lus nthuav dav kom txo cov dej kub, thiab cia txias ntau rau hauv qhov sib tov . Qhov twg yog qhov zoo dua qhov sib npaug lossis ntsuas kub?
Yuav kub kub kub kub li cas?
Capsaicin tuaj yeem ua rau kub hnyiab tau qhov twg los xij. Txawm hais tias cov tshuaj nkag mus rau ntawm qhov chaw uas tsis yog koj cov tawv nqaij, koj yuav hnov mob thaum koj tom qab kov qhov chaw ntawd. Qhov kev hnov qab no feem ntau yog me me thiab yuav tsum maj mam txo qis thaum lub sijhawm nrog kev siv cov tshuaj txuas ntxiv mus.

"Koj tuaj yeem muaj lub suab kaw zoo tshaj plaws ntawm txhua lub sijhawm, tab sis yog tias koj ua si nrog tus nqi qis, nws yuav ua suab tsis zoo rau lwm qhov kawg.
Koj puas tuaj yeem ntxuav qhov kub ntawm qhov hluav taws kub?
Nws tsis tas yuav ntxuav qhov kub ntawm qhov hluav taws kubvim nws tshuab tawm cov plua plav tawm. Txawm li cas los xij sib txawv ntawm silicon carbide ceramic kub nto ignitor uas yog nkig heev thiab yuav tsum tsis txhob kov, silicon nitride kub nto ignitor muaj zog heev thiab tuaj yeem ntxuav manually yog tias tsim nyog .
