Sib npaug hydrogens yog H-atoms uas hloov pauv tau tag nrho raws li lawv lub luag haujlwm hauv molecule. Nyob rau hauv rooj plaub ntawm HNMR, ob Hydrogens yog carbon 1 sib npaug vim lawv muab tib lub teeb liab ntawm lub spectrum. Cov Hydrogens yog carbon 2 sib npaug rau ib leeg.
Ib yam li ntawd, dab tsi yog hydrogens tsis sib npaug?
Basic Vocabulary: Sib npaug Protons : protons uas zoo ib yam nyob rau hauv txhua txoj kev. Lawv muaj tib qhov chaw sib nqus, uas ua rau lawv tib lub zog tig tig. Tsis sib xws Protons : protons uas tsuas yog yuav tsum sib txawv ntawm ib txoj kev. Cov no protons tsis muaj qhov sib nqus ib puag ncig.
Tsis tas li ntawd, puas sib npaug hydrogens cais? Tshuaj sib npaug protons ua tsis yog khub niam txiv. (Yog vim li cas protons ntawm tib C ua tsis yog cais ib leeg.) Ntawm no yog ib qho piv txwv ntawm cov molecule uas nws protons yog txhua yam tshuaj sib npaug . NMR absorption spectrum yuav muaj ib lub ncov.
Raws li, qhov chaw hydrogen yog dab tsi?
Qhov no yog hais txog cov qauv ntawm cov molecule. Cov tshuaj hloov pauv thiab cov qauv sib cais ntawm H atom hauv HNMR specrum muab cov ntaub ntawv hais txog lwm cov atoms nyob ze. Functional pawg nyob ib sab ntawm lub hydrogen suav nws ib puag ncig . Functional pawg nyob ib sab ntawm lub hydrogen suav nws ib puag ncig.
Yuav ua li cas koj thiaj paub yog tias carbon sib npaug?
1. Tus naj npawb ntawm cov cim qhia peb yog muaj sib npaug carbons . a. Yog tus naj npawb ntawm cov teeb liab yog tsawg dua li tag nrho cov naj npawb ntawm carbons nyob rau hauv lub molecule, muaj tsawg kawg yog ib khub ntawm sib npaug carbons.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Qhov sib npaug sib npaug rau qhov nruab nrab ntawm h2so4 los ntawm Koh yog dab tsi?
Hauv daim vis dis aus no peb yuav sib npaug ntawm qhov sib npaug KOH + H2SO4 = K2SO4 + H2O thiab muab cov coefficients raug rau txhua qhov sib xyaw. Txhawm rau sib npaug KOH + H2SO4 = K2SO4 + H2O koj yuav tsum nco ntsoov suav tag nrho cov atoms ntawm txhua sab ntawm cov tshuaj sib npaug
Puas yog txhua qhov sib npaug sib npaug sib npaug?
Thawj qhov sib npaug sib npaug yog qhov tseeb yog tias nws muaj kev txuag kom muaj nuj nqis. Piv txwv li, qhov sib npaug sib cais yeej ib txwm muaj tseeb, txij li lub ntsiab lus lawv yog ntawm daim ntawv: M(y) + N(t) = 0, yog li ϕ(t, y) = A(y) + B(t) yog a khaws cia kom muaj nuj nqis
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
