Piv txwv li, NaCl muaj lub sijhawm dipole siab tshaj plaws vim nws muaj ionic daim ntawv cog lus (piv txwv li kev sib cais siab tshaj plaws). Hauv Chloromethane Chloromethane Chloromethane, tseem hu ua methyl chloride, Refrigerant-40, R-40 lossis HCC 40, yog cov organic compound nrog cov tshuaj formula CH 3 Cl. Ib qho ntawm cov haloalkanes, nws yog ib qho tsis muaj xim, tsis muaj ntxhiab, flammable gas. Methyl chloride yog ib qho tseem ceeb reagent nyob rau hauv industrial chemistry, txawm hais tias nws tsis tshua muaj nyob rau hauv cov neeg siv khoom. https://en.wikipedia.org › wiki › Chloromethane
Chloromethane - Wikipedia
molecule (CH3Cl), chlorine yog electronegative ntau dua carbon, yog li nyiam cov electrons hauv C-Cl daim ntawv cog lus rau nws tus kheej (Daim duab 1).
Qhov twg hauv qab no muaj qhov siab tshaj plaws dipole lub sijhawm?
Vim tias, qhov sib txawv ntawm electronegativity yog qhov siab tshaj plaws nyob rau hauv cov ntaub ntawv ntawm N-H daim ntawv cog lus, yog li NH3 muaj lub sijhawm dipole siab tshaj plaws.
Yuav ua li cas cov compound muaj ntau tshaj dipole?
Txhua yam yog isostructural tab sis NH3 yog ua los ntawm N thiab H. Electronegativity sib txawv ntawm N thiab H yog siab tshaj plaws ntawm tag nrho cov, li no NH3 muaj siab tshaj dipole lub sij hawm.
Qhov twg muaj lub sijhawm dipole siab tshaj CH2Cl2 CHCl3 CCl4?
Nws muaj lub sijhawm dipole siab tshaj plaws thiab muab qhov kev txiav txim CH3Cl, CH2Cl2, CHCl3 lossis CCl4. Qhov kev txiav txim ntawm kev txo dipole lub sij hawm yog CH3Cl> CH2Cl2 > CHCl3> CCl4. Lub sijhawm net dipole ntawm CCl4 yog xoom vim tias plaub C-Cl daim ntawv cog lus dipolestso tseg ib leeg.
Qhov twg muaj qhov siab tshaj plaws dipole lub sijhawm NH3 lossis NF3?
→NH3 muaj ntau dua dipole lub sijhawm tshaj NF3. » CEEB TOOM: nyob rau hauv cov ntaub ntawv ntawm NH3, nitrogen yog ntau electronegative tshaj hydrogen, yog li nws sim rub cov electrons los ntawm hydrogen atoms. qhov twg ib yam li NF3, fluorine yog electronegative ntau dua nitrogen sim rub cov electrons los ntawm nitrogen opposite ntawm nitrogen.
