Esters
| Compound npe | Tshuaj tsw qab | Ntuj tshwm sim |
|---|---|---|
| Methyl butyrate Methyl butanoate | Fruity, Kua Pineapple | Pineapple |
| Ethyl acetate hmoov | Qab zib, hnyav | Caw |
| Ethyl butyrate Ethyl butanoate | Fruity, Txiv kab ntxwv Pineapple | |
| Isoamyl acetate hmoov | Fruity, Txiv tsawb Pear | Txiv tsawb cog |
Nyob rau hauv no hais txog, dab tsi yog ib co chav kawm ntawm cov organic tebchaw uas muaj tsis kaj siab tsw?
Aroma Compounds los ntawm Organic Structure
| tsw | Ntuj qhov chaw | |
|---|---|---|
| methyl butyrate | txiv hmab txiv ntoo, pineapple, txiv apples | pineapple |
| ethyl acetate hmoov | qab zib hnyav | cawv |
| yogoamyl acetate | txiv tsawb, txiv tsawb, txiv tsawb | txiv tsawb |
| benzyl acetate hmoov | fruity, strawberry | strawberry |
Ib tug kuj yuav nug, vim li cas cov organic tebchaw muaj tsw? Cov kws tshawb fawb paub tias aroma molecules, los yog odorants, khi rau olfactory receptors (ORs) uas zaum nyob rau hauv ib txheej ntawm mucus nyob rau sab sauv ntawm lub qhov ntswg. Ntau ntau organic tebchaw muaj qhov zoo no yog li feem ntau cov tub ntxhais hluas chemists ntsib qee yam tsw thaum lawv kawm tiav qib kaum ob lossis qib kawm chemistry.
cov organic tebchaw puas muaj ntxhiab tsw?
SVOCs (semi volatile organic tebchaw ) yog odorless compounds uas caij cov plua plav thiab nce ntxiv rau lub sijhawm thaum lawv maj mam tso tawm ntawm cov ntaub ntawv xws li rwb thaiv tsev, rooj tog zaum, qee yam cookware, tshuaj tua kab, thiab ntau lwm yam khoom.
alkenes tsw zoo li cas?
Alkenes feem ntau muaj zog dua tsw tsw tshaj qhov sib thooj alkane. Ethylene tau piav qhia tias muaj "qab zib" tsw, thaum ethane tsis muaj ntxhiab, piv txwv li. Kev khi ntawm cupric ion mus rau olefin hauv mammalian olfactory receptor MOR244-3 yog cuam tshuam nrog tsw ntawm alkenes (zoo li thiols).

Yuav ua li cas koj txiav txim siab yog hais tias ib tug muaj nuj nqi muaj ib tug kab rov tav tangent?
Kab rov tav kab muaj txoj kab nqes ntawm xoom. Yog li ntawd, thaum lub derivative yog xoom, cov kab tangent yog kab rov tav. Txhawm rau nrhiav cov kab kab rov tav tangent, siv qhov derivative ntawm txoj haujlwm los nrhiav qhov xoom thiab ntsaws lawv rov qab rau hauv qhov sib npaug qub
Yuav ua li cas koj sau cov mis rau ib tug compound uas muaj ib tug polyatomic ion?
Txhawm rau sau cov qauv rau cov tebchaw uas muaj polyatomic ions, sau lub cim rau cov hlau ion ua raws li cov qauv rau polyatomic ion thiab sib npaug cov nqi. Txhawm rau sau npe ib qho chaw uas muaj polyatomic ion, hais cov cation ua ntej thiab tom qab ntawd cov anion
Yuav ua li cas tshwm sim thaum koj sib tov ib tug muaj zog acid nrog ib tug tsis muaj zog puag?
Hom 2: thaum muaj zog acid / base reacts nrog lub hauv paus tsis muaj zog / acid yog hydronium thiab hydroxyl ions tam sim no nyob rau hauv sib npaug amt ces ntsev thiab dej yog tsim thiab lub zog tso tawm uas tsawg tshaj li 57 kj / mole vim lub dissociation ntawm lub tsis muaj zog acid / puag uas feem ntau endothermic
Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab cov khoom siv organic?
Dab tsi yog qhov txawv ntawm cov khoom siv organic thiab organic teeb meem? Organic khoom yog txhua yam uas tseem muaj sia nyob thiab tam sim no nyob rau hauv lossis hauv av. Rau nws los ua cov organic teeb meem, nws yuav tsum tau decomposed rau hauv humus. Humus yog cov khoom siv organic uas tau hloov dua siab tshiab los ntawm cov kab mob mus rau lub xeev tsis muaj zog
