Van der Waals Kev Sib Tham . van der Waals kev sib cuam tshuam tshwm sim Thaum cov atoms uas nyob ib sab tuaj ze txaus uas lawv cov huab cua sab nraud tsuas yog kov xwb. Qhov kev txiav txim no ua rau muaj kev hloov pauv uas ua rau muaj qhov tsis zoo, tsis muaj kev cuam tshuam. Thaum ob lub atoms ze heev, lawv tawm tsam ib leeg.

Tib neeg kuj nug tias, piv txwv li cas ntawm van der Waals force?

Van der Waals rog yog cov tsis muaj zog zog uas ua rau muaj kev sib txuas ntawm kev sib txuas ntawm cov molecules. Piv txwv ntawm van der Waals rog muaj xws li hydrogen bonding, dispersion zog , thiab dipole-dipole kev sib cuam tshuam.

Ib tug kuj yuav nug, vim li cas van der Waals kev sib cuam tshuam tseem ceeb? Hauv Protein folding www.intechopen.com Vander waals sib cuam tshuam yog lwm tus tseem ceeb bonding hom uas pab stabilizing cov qauv protein. Hauv coiled-coil protein, muaj kev sib tham nruab nrab ntawm sab saw hauv alpha helix.

Ua raws li qhov no hauv kev xav, yuav ua li cas van der Waals tsim?

Txhais. Van der Waals cov rog muaj xws li attraction thiab repulsions ntawm atoms, molecules, thiab nto, nrog rau lwm yam intermolecular rog. Lawv txawv ntawm covalent thiab ionic bonding nyob rau hauv uas lawv yog tshwm sim los ntawm correlations nyob rau hauv lub fluctuating polarizations nyob ze hais (ib tug tshwm sim ntawm quantum dynamics).

Van der Waals rog nyob qhov twg?

Zoo, Van der Waals rog yog tam sim no nyob rau hauv tag nrho cov kev sib cuam tshuam ntawm covalent molecules thiab non-metals. Raws li kev ceeb toom, tej zaum koj tau hnov txog li cas cov dej molecules cuam tshuam los ntawm qhov muaj zog heev Van Der Waals , hydrogen bonding.
