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.
