Alkenes yog lub npe hu ua Olefins vim ethylene, uas yog thawj tus tswv cuab hauv cov tshuaj alkene tseem hu ua ethene tau pom los ua cov khoom lag luam oily thaum lawv tau ua los cuam tshuam nrog chlorine thiab bromine.
Puas yog alkenes olefins?
Vim tias alkenes muaj tsawg dua li qhov siab tshaj plaws ntawm hydrogen atoms ib carbon atom, lawv tau hais tias yog unsaturated. Ib lo lus qub uas tseem siv hauv kev lag luam roj av los xaiv alkenes yog olefins (saib lub thawv ntawv).
olefin txhais li cas?
olefin, tseem hu ua alkene, cov khoom xyaw ua los ntawm hydrogen thiab carbon uas muaj ib lossis ntau khub ntawm carbon atoms txuas los ntawm ob daim ntawv cog lus. Olefins yog cov piv txwv ntawm unsaturated hydrocarbons (cov tshuaj uas tsuas muaj hydrogen thiab carbon thiab tsawg kawg yog ib ob lossis triple daim ntawv cog lus).
Dab tsi yog qhov txawv ntawm olefins thiab alkenes?
yog tias alkene yog (organic chemistry) unsaturated, aliphatic hydrocarbon nrog ib lossis ntau dua carbon-carbon ob daim ntawv cog lus thaum olefin yog (organic chemistry) ib chav kawm ntawm unsaturated open-chain hydrocarbons xws li ethylene; ib qho alkene nrog tsuas yog ib qho carbon-carbon ob daim ntawv cog lus.
Vim li cas alkynes hu ua acetylene?
Vim li cas alkyne hu ua acetylene? Hais txog hydrogen atoms, vim cov compound yog unsaturated, cov electrons ntxiv tau pauv los ntawm 2 carbon atoms uas tsim ob daim ntawv cog lus. Alkynes los ntawm thawj compoundnyob rau hauv cov kab ke kuj tseem hu ua ACETYLENES.
