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.
