IUPAC Cov cai rau Alkane Nomenclature
Qhia thiab npe pab pawg txuas nrog cov saw no. Sau cov saw txuas txuas ntxiv, pib ntawm qhov kawg ze tshaj ib pab pawg hloov pauv. Xaiv qhov chaw ntawm txhua pab pawg neeg hloov pauv los ntawm tus lej tsim nyog thiab npe . Sib sau ua ke npe , teev cov pab pawg nyob rau hauv alphabetical order.
Tsis tas li ntawd, ua li cas koj muab lub npe Iupac rau ib qho chaw?
Hauv cov ntsiab lus, cov npe ntawm compound yog sau tawm nrog cov hloov pauv hauv cov ntawv sau ua raws li lub hauv paus npe (muab los ntawm tus naj npawb ntawm carbons nyob rau hauv niam txiv saw). Commas yog siv los ntawm cov lej thiab cov dashes yog siv ntawm cov tsiaj ntawv thiab cov lej.
Qhov thib ob, cov organic tebchaw hu ua li cas? Compound naming kauj ruam
- Kauj Ruam 1: Nrhiav qhov ntev tshaj plaws carbon saw nyob rau hauv peb lub compound. Peb yuav siv qhov sib xyaw no ua peb tus piv txwv rau npe.
- Kauj Ruam 2: Lub npe uas ntev tshaj plaws carbon saw.
- Kauj Ruam 3: Txheeb xyuas qhov xaus (suffix) yuav tsum yog dab tsi.
- Kauj Ruam 4: Sau koj cov carbon atoms.
- Kauj Ruam 5: Sau npe cov pab pawg sab.
Ib yam li ntawd, nws yog nug, ua li cas koj lub npe sab chains?
Cov kauj ruam rau Naming Branched-Chain Alkanes
- Lub npe qia, qhov ntev tshaj plaws carbon saw ua ntej. Lub qia ntawm branched-chain alkane muaj npe nyob rau hauv tib txoj kev raws li koj tau kawm rau npe ncaj saw alkanes.
- Txheeb xyuas cov ceg ntoo uas tshwm sim raws li qhov ntev ntawm lub qia (qhov ntev tshaj plaws carbon saw).
- Sau npe txhua ceg (los yog sab saw).
ch3 hu li cas?
Ib pawg methyl yog ib qho alkyl muab tau los ntawm methane, muaj ib qho carbon atom sib txuas rau peb hydrogen atoms - CH3 . Hauv cov qauv, cov pab pawg feem ntau abbreviated Me. Xws li hydrocarbon pawg tshwm sim nyob rau hauv ntau cov organic tebchaw. Nws yog ib pab pawg ruaj khov heev hauv feem ntau cov molecules.

Yuav ua li cas koj pom lub kaum sab xis nruab nrab muab qhov chaw thiab lub vojvoog ntawm ib lub sector?
Kev txiav txim siab Central Angle Los ntawm Sector Area (πr2) × (central angle in degrees ÷ 360 degrees) = sector area. Yog hais tias lub hauv paus lub kaum sab xis ntsuas nyob rau hauv radians, lub mis hloov mus ua: sector cheeb tsam = r2 × (central kaum hauv radians ÷ 2). (θ ÷ 360 degree) × πr2. (52.3 ÷ 100π) × 360. (52.3 ÷ 314) × 360
Lub npe muab rau tus qauv ntawm pob zeb diamond yog dab tsi?
Crystal Structure. Cov qauv siv lead ua ntawm lub pob zeb diamond yog lub ntsej muag-centered cubic lossis FCC lattice. Txhua cov pa roj carbon atom koom nrog plaub lwm cov pa roj carbon atom hauv tetrahedrons tsis tu ncua (triangular prisms)
Dab tsi yog lub npe uas muab rau kev sib raug zoo symbiotic uas ob hom tau txais txiaj ntsig?
Mutualism yog ib qho kev sib raug zoo uas ob hom tau txais txiaj ntsig. Commensalism yog ib qho kev sib raug zoo uas ib hom tau txais txiaj ntsig thaum lwm hom tsis cuam tshuam. Parasitism yog ib qho kev sib raug zoo uas ib hom (cov kab mob cab) tau txais txiaj ntsig thaum lwm hom (tus tswv tsev) raug mob
Cov organic tebchaw tau txais lawv lub npe Li cas lo lus muaj feem xyuam rau nws lub ntsiab lus li cas?
Lo lus hais txog nws lub ntsiab lus li cas? Organic Compounds tau txais nws lub npe los ntawm tus lej ntawm cov ntawv cog lus carbon. Lo lus muaj feem xyuam rau lub ntsiab lus vim hais tias nws yuav tsum tau ua nrog bonds nyob rau hauv carbon atoms nyob rau hauv cov organic tebchaw
Yuav ua li cas tshwm sim rau lub parallel phaj capacitor thaum lub dielectric muab tso rau ntawm daim hlau?
Thaum cov khoom siv dielectric tau qhia nruab nrab ntawm daim hlau Thiab thaum cov khoom siv dielectric muab tso rau nruab nrab ntawm daim hlau ntawm cov paib sib npaug ntawm cov phaj capacitor ces vim polarization ntawm cov nqi ntawm ob sab ntawm dielectric, nws tsim hluav taws xob teb ntawm nws tus kheej uas ua nyob rau hauv ib qho kev taw qhia opposite. rau lub teb vim
