Molecular geometry yog qhov kev npaj peb-dimensional ntawm cov atoms uas yog a molecule . Nws suav nrog cov general puab ntawm molecule nrog rau qhov ntev ntawm daim ntawv cog lus, daim ntawv cog lus, lub kaum sab xis thiab lwm yam geometrical tsis uas txiav txim siab txoj haujlwm ntawm txhua lub atom.

Kuj paub yog, dab tsi yog qhov zoo li hauv chemistry?

Molecules muaj cov duab . Muaj ntau yam pov thawj ntawm kev sim rau qhov tshwm sim-los ntawm lawv lub cev rau lawv tshuaj reactivity. Me me molecules-molecules nrog ib lub hauv paus atom-muaj cov duab uas tuaj yeem kwv yees tau yooj yim. Qhov no puab yog hu ua bent los yog angular.

Tsis tas li ntawd, vim li cas cov duab molecular tseem ceeb hauv chemistry? A molecule muaj tus yam ntxwv loj thiab puab . Qhov tseeb puab ntawm a molecule feem ntau yog heev tseem ceeb rau nws txoj haujlwm hauv lub cell muaj sia. Molecular puab Nws yog ib qho tseem ceeb hauv biology vim nws txiav txim siab li cas biological molecules lees paub thiab teb rau ib leeg nrog qhov tshwj xeeb.

Ib yam li ntawd, koj tuaj yeem nug, cov duab ntawm cov molecules yog dab tsi?

Lub tsib zoo tagnrho cov duab yog: linear, trigonal planar, tetrahedral, trigonal bypramidal thiab octahedral. Ib qho tseem ceeb uas yuav tsum nco ntsoov txog molecular zoo yog tias tag nrho cov diatomic (sib xyaw nrog ob lub atoms) cov kab sib txuas.

Koj pom cov duab molecular li cas?

Cov kauj ruam siv los nrhiav cov duab ntawm cov molecule

  1. Kos tus qauv Lewis.
  2. Suav tus naj npawb ntawm cov pab pawg electron thiab txheeb xyuas lawv raws li daim ntawv cog lus ntawm pawg hluav taws xob lossis ib leeg ntawm cov hluav taws xob.
  3. Lub npe electron-group geometry.
  4. Saib ntawm txoj hauj lwm ntawm lwm cov atomic nuclei nyob ib ncig ntawm lub hauv paus txiav txim siab cov molecular geometry.
