Kev sib koom tsis sib xws ntawm cov hluav taws xob ua rau dej tus polar molecule. … Qhov no txhais tau hais tias electrons siv sij hawm me ntsis ntxiv ntawm cov pa oxygen kawg ntawm cov molecule. Qhov no ua rau cov pa kawg ntawm cov molecule tsis zoo me ntsis. Txij li thaum cov electrons tsis nyob ze hydrogen kawg li ntau, qhov kawg yog me ntsis zoo.
Vim li cas dej polar heev?
Vim cov pa oxygen muaj cov hluav taws xob ntau dua li hydrogen, cov hluav taws xob ntawm cov molecule zoo li pab pawg ze rau cov pa ntau dua li hydrogen atoms. … Yog li ntawd, dej tau hais tias yog "polar" molecule, uas txhais tau hais tias muaj kev faib tsis sib npaug ntawm electron ceev.
Vim li cas H2O polar?
Dej (H2O) yog polar vim qhov khoov ntawm cov molecule. … Lub molecule yog tsim los ntawm ob lub hydrogen atoms thiab ib tug oxygen atom. Thaum ob lub molecules dej nyob ze ua ke, cov polar rog ua haujlwm los kos cov molecules ua ke.
Vim li cas dej thiaj nyiam qhov zoo thiab qhov tsis zoo?
Tus nqi zoo me ntsis ntawm hydrogen atoms hauv cov dej molecule nyiam cov nqi tsis zoo me ntsis ntawm cov pa oxygen ntawm lwm cov dej molecules. Lub zog me me ntawm kev nyiam no yog hu ua hydrogen bond. Daim ntawv cog lus no tsis muaj zog heev.
Dab tsi ua rau daim ntawv cog lus polar?
Polar Covalent Bonds. Covalent daim ntawv cog lus muaj nyob thaum 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.
