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…
Yuav ua li cas koj thiaj paub yog tias ib lub molecule tsis saturated?
Ib lub molecule uas yog cov alkene lossis alkyne homologous series yog ib qho tsis muaj hydrocarbon. Cov pa roj carbon atoms tuaj yeem npaj rau hauv cov saw ncaj, cov saw hlau, lossis hauv cov nplhaib (cyclic compounds), raws li ntev raws li muaj tsawg kawg yog 1 ob daim ntawv cog lus (C=C) thiab /lossis 1 triple bond (C≡C) cov molecule yuav tsis saturated.
qib tsis txaus ntseeg txhais li cas?
Nyob rau hauv kev tshuaj xyuas ntawm cov mis molecular ntawm cov organic molecules, qhov degree ntawm unsaturation (tseem hu ua qhov ntsuas ntawm hydrogen deficiency (IHD), ob daim ntawv cog lus sib npaug, lossis qhov ntsuas tsis txaus ntseeg) yog kev suav tias txiav txim siab tag nrho cov nplhaib thiab π daim ntawv cog lus.
Qhov twg ntawm cov qauv hauv qab nonta pab txhawb rau qib ntawm unsaturation ntawm ib tug molecule?
Ib daim ntawv cog lus ob npaug , ib qib ntawm kev tsis txaus ntseeg Ib yam li kev tsim ntawm ob daim ntawv cog lus ua rau ob lub hydrogens ploj, qhov tsim ntawm lub nplhaib kuj tau txais txiaj ntsig. nyob rau hauv qhov poob ntawm ob hydrogens, yog li txhua lub nplhaib nyob rau hauv lub molecule kuj ntxiv ib tug degree ntawm unsaturation.

Ib tug neeg xam xaj Asmeskas yog tus neeg yug los txawv tebchaws uas tau ua tiav txhua qhov kev xav tau los ua neeg xam xajtsim los ntawm Txoj Cai Kev Nkag Tebchaws thiab Kev Ua Haujlwm Zoo (INA) dhau los ntawm US Congress.
Qhov twg yog qhov kev sib raug zoo ntawm stereochemical ntawm ob khub ntawm cov molecules?
Enantiomers thiab diastereomers tsuas yog ob qho kev sib raug zoo stereochemical uas koj tuaj yeem muaj ntawm ob lub molecules. Cov stereoisomers yog ob lub molecules uas ua tiav ob qhov kev xav tau hauv qab no: Ob lub molecules yuav tsum muaj tib lub qauv molecular, thiab.
