Lub molecular geometry ntawm BCl3 yog trigonal txoj kev nrog symmetric nqi faib nyob ib ncig ntawm lub hauv paus atom. Yog li no molecule yog nonpolar.

Tsis tas li ntawd, tus qauv ntawm BCl3 yog dab tsi?

BCl3 yog ib tug trigonal planar molecule zoo li lwm yam boron trihalides, thiab muaj ib daim ntawv cog lus ntev ntawm 175 teev. Nco ntsoov tias Boron tuaj yeem muaj tag nrho sab nraud nrog rau tsuas yog rau valence electrons. Hauv Lewis qauv rau BCl3 lub hauv paus atom (Boron) yuav tsuas muaj rau valence electrons.

Ib yam li ntawd, yog BCl3 polar lossis nonpolar? Boron trichloride, los yog BCl3 , yog tsis muaj polar . Peb lub chloride atoms muaj qhov tsis zoo, thiab ib qho boron nyob hauv nruab nrab muaj qhov sib npaug tab sis zoo. Boron zaum nyob rau hauv nruab nrab ntawm lub molecule thiab muaj peb valence electrons, yog li nws sib npaug tawm peb chlorides.

Ua raws li qhov kev pom no, vim li cas BCl3 thiaj li muaj cov qauv trigonal?

BCl3 muaj 3 B-Cl ib daim ntawv cog lus thiab tsis muaj ib khub nyob ib puag ncig B, li no 6 valence electrons nyob ib ncig ntawm B. Raws li ib daim ntawv VSEPR, cov molecule no siv AX3 cim. Geometry ntawm BCl3 yog trigonal txoj kev . AlCl3 muaj 3 Al-Cl ib daim ntawv cog lus thiab tsis muaj ib leeg ib ncig ntawm Al, li no 6 valence electrons nyob ib ncig ntawm Al.

Dab tsi yog daim ntawv cog lus lub kaum sab xis hauv BCl3?

BCl3 Molecular Geometry Thiab Bond Angles Yog tias peb saib cov qauv, BCl3 molecular geometry yog trigonal planar. Cov daim ntawv cog lus yog 120o.
