Txhawm rau tsim cov roj hluav taws xob tsis zoo, txhua lub atom hauv HCl xav tau ib qho hluav taws xob ntxiv. … Qhov loj ntawm lub atom, xav txog nws cov electronegativity, yog li hais tias nws cov electron ceev yog tsawg heev rau hydrogen bonds tsim. Qhov no yog vim li cas, thaum HF ua, HCl tsis qhia hydrogen bonding.
H2S puas yog daim ntawv cog lus hydrogen?
Piv txwv li, xav txog hydrogen sulfide, H2S, ib lub molecule uas muaj tib yam li dej tab sis tsis muaj hydrogen bonds. Vim nws qhov tsis muaj zog intermolecular rog, H2S boils ntawm −60 ° C thiab yog li yog ib qho roj ntawm chav tsev kub.
Yuav ua li cas daim ntawv cog lus yog hydrogen chloride?
Polar Covalent Bonds. Daim ntawv cog lus polar covalent tshwm sim thaum cov atoms nrog cov electronegativities sib txawv sib koom cov khoom siv hluav taws xob hauv cov ntawv cog lus. Xav txog hydrogen chloride (HCl) molecule. Txhua lub atom hauv HCl xav tau ib qho hluav taws xob ntxiv los tsim ib qho hluav taws xob hluav taws xob inert.
Vim li cas HCl tsis tuaj yeem tsim cov ntawv cog lus hydrogen?
Qhov loj ntawm lub zog ntawm qhov sib xyaw ua ke kuj tau qhia nyob rau hauv cov ntsiab lus kub ib txwm muaj… HF, 19.5 ∘C piv …… chlorine yog atom loj, ua HCl muaj qhov ntsuas electronegativity siab, uas tsis tseem ceeb txaus los tsim ib daim ntawv cog lus hydrogen.
Puas ch3ch3 yog ib daim ntawv cog lus hydrogen?
No, tsis muaj hydrogen bonds hauv CH3-CH3 (ethane). Qhov no yog vim tias carbon thiab hydrogen muaj qhov sib xwselectronegativities.
