Cov pa roj carbon-hydrogen bond (C-H daim ntawv cog lus) yogkhi ntawm carbon thiab hydrogen atomsuas tuaj yeem pom muaj nyob hauv ntau cov organic tebchaw. Daim ntawv cog lus no yog covalent daim ntawv cog lus lub ntsiab lus uas carbon qhia nws cov valence electrons sab nraud nrog txog plaub hydrogens. Qhov no ua tiav ob qho tib si ntawm lawv lub plhaub sab nrauv ua rau lawv ruaj khov.
H thiab CI puas yog daim ntawv cog lus?
Hydrogen thiab carbon muaj qhov zoo sib xws ntawm electronegativity, yog li C- H daim ntawv cog lus tsis yog ib txwm suav tias yog daim ntawv cog lus cog lus. Yog li ethane, ethylene, thiab acetylene muaj nonpolar covalent bonds, thiab cov tebchaw yog nonpolar.
Puas C tsim daim ntawv cog lus covalent?
Carbon tsim covalent daim ntawv cog lus nrog atoms ntawm carbon lossis lwm yam ntsiab. Muaj ntau qhov sib txawv ntawm cov pa roj carbon monoxide, xws li qhov loj me los ntawm ib mus rau txhiab tus atoms. Cov pa roj carbon muaj plaub qhov hluav taws xob valence, yog li nws tuaj yeem ua tiav tag nrho sab nrauv lub zog los ntawm kev tsim plaub daim ntawv cog lus.
Puas yog C thiab H nonpolar covalent daim ntawv cog lus?
C-H daim ntawv cog lus yog li ntawd xav tsis pom zoo. Ob lub hydrogen atoms muaj tib lub electronegativity tus nqi-2.1. Qhov txawv yog xoom, yog li daim ntawv cog lus yog nonpolar.
H puas yuav tsim daim ntawv cog lus?
Hydrogen tuaj yeem koom nrog ob qho tib si ionic thiab covalent bonding. Thaum koom nrog covalent bonding, hydrogen tsuas yog xav tau ob lub tshuab hluav taws xob kom muaj lub plhaub valence tag nrho. Raws li nws tsuas muaj ib qho hluav taws xob pib nrog, nws tsuas yog ua tau ib qho xwbdaim ntawv cog lus.
