Carbon tetrachloride, tseem paub los ntawm ntau lwm lub npe yog cov organic compound nrog cov tshuaj formula CCl₄. Nws yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw "qab zib" uas tuaj yeem kuaj pom ntawm qib qis. Nws yog xyaum tsis flammable ntawm qhov kub thiab txias.
Puas yog tetrachloromethane ionic lossis covalent?
(b) Tetrachloromethane yog ib qho yooj yim molecular, covalent compound. Cov mis ntawm nws cov molecule yog CCl4. Muaj plaub lub electrons nyob rau hauv lub plhaub sab nraud ntawm ib tug carbon atom. Muaj xya lub electrons nyob rau hauv lub plhaub sab nraud ntawm ib lub chlorine atom.
YPuas yog tetrachloromethane ionic?
Cov nyiaj tau los ntawm carbon thiab chlorine yog covalent daim ntawv cog lus vim nws yog tsim los ntawm kev sib koom electrons. Qhov no ua rau CCl4 a covalent compound.
Yuav ua li cas daim ntawv cog lus yog tetrachloromethane?
Lewis Dot ntawm Carbon TetraChloride CCl4 TetraChloromethane. Nyob rau hauv cov pa roj carbon tetrachloride molecule, plaub chlorine atoms yog positioned symmetrically raws li cov ces kaum nyob rau hauv ib tug tetrahedral configuration koom nrog ib tug central carbon atom los ntawm ib leeg covalent bonds Vim yog qhov symmetrical geometry, CCl 4 tsis yog polar.
Vim li cas CCl4 tsis yog ionic compound?
HCl thiab CCl4 yog covalent compounds; yog li lawv tsis tuaj yeem ua ionic. … Vim tias ob lub atom sib koom ib khub ntawm electrons, hydrochloric acid (HCl) thiab carbon tetrachloride (CCl 4) tsim covalent bonds Vim lawv muaj qhov zoo thiab Tsis zoo ions, sodium chloride (NaCl) thiab potassium chloride (KCl) tsim ionic compounds.
