Qhov degree ntawm unsaturation qhia tag nrho cov pi bonds pi bonds Ib daim ntawv cog lus pi yog cov tshuaj tsis muaj zog cov khoom siv nyiaj ntau dua li daim ntawv cog lus sigma(vim π bonds muaj qhov sib tshooj me me ntawm lub orbitals), tab sis thaum nws muab tso nrog ib tug sigma daim ntawv cog lus nws tsim ib tug ntau zog tuav ntawm atoms, yog li ob thiab triple daim ntawv cog lus muaj zog dua ib daim ntawv cog lus. https://chem.libretexts.org › Non-Singular_Covalent_Bonds

thiab rings nyob rau hauv ib lub molecule uas ua rau nws yooj yim rau ib tug los xam cov qauv molecular.
Koj pom qhov ntsuas qhov tsis txaus ntseeg li cas?
Degrees ntawm unsaturation yog sib npaug rau 2, los yog ib nrab ntawm cov hydrogens cov molecule yuav tsum tau muab cais raws li saturated. Li no, cov qauv DoB faib los ntawm 2. Cov mis rho tawm tus lej X vim tias halogen (X) hloov cov hydrogen hauv ib qho chaw.
Vim li cas peb suav cov degree ntawm unsaturation?
Txawm hais tias, nuclear magnetic resonance (NMR) thiab infrared radiation (IR) yog thawj txoj hauv kev txiav txim siab cov qauv molecular, xam cov qib ntawm unsaturation yog cov ntaub ntawv tseem ceeb txij li thaum paub txog qib ntawm unsaturation ua kom yooj yim dua. rau ib qho los txheeb xyuas cov qauv molecular; nws pab ib ob-kos…
Qib 11 tsis txaus ntseeg yog dab tsi?
Unsaturation txhais tau tias muaj ob daim ntawv cog lus lossis triple daim ntawv cog lus. Nws yogsiv los xam cov rings thiab pi bonds tam sim no nyob rau hauv ib lub molecule. Ua kom tiav cov lus teb ib kauj ruam: … Tag nrho cov degree ntawm unsaturation yog 3+6+2=11.
Dab tsi yog siv cov degree ntawm unsaturation?
Qib tsis txaus (tseem hu ua qhov ntsuas ntawm hydrogen deficiency (IHD) lossis rings ntxiv rau ob daim ntawv cog lus) cov qauv siv hauv cov tshuaj lom neeg los pab kos cov qauv tshuaj. Cov mis cia tus neeg siv txiav txim seb muaj pes tsawg lub nplhaib, ob daim ntawv cog lus, thiab peb daim ntawv cog lus muaj nyob rau hauv qhov sib xyaw kom tau kos.
