Lub npe Dienes

Ua ntej txheeb xyuas cov saw ntev tshaj plaws uas muaj ob qho tib si carbons nrog ob daim ntawv cog lus hauv qhov sib xyaw. Tom qab ntawd muab tus lej qis tshaj plaws rau qhov chaw ntawm carbons nrog ob daim ntawv cog lus thiab lwm pab pawg ua haujlwm tam sim no (nco ntsoov thaum npe alkenes uas qee cov pab pawg muaj qhov tseem ceeb xws li cawv).

Ib yam li ntawd, dab tsi yog Dienes li cas lawv raug cais?

Dienes tsuas yog hydrocarbons xwb uas muaj ob daim ntawv cog lus. Dienes yog nruab nrab ntawm alkenes thiab polyenes. Dienes ua tau faib rau hauv peb chav kawm: Unconjugated cov dyes muaj ob daim ntawv cog lus sib cais los ntawm ob lossis ntau dua ib daim ntawv cog lus. Cov no tseem hu ua cais cov dyes.

Tsis tas li ntawd, ch3 hu ua dab tsi? 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 hauv feem ntau cov molecules.

Tsis tas li ntawd, dab tsi yog ib qho diene cais?

Isolated Diene Lus Txhais: Ib qho kev sib xyaw uas muaj ob daim ntawv cog lus carbon-carbon p uas sib cais los ntawm ob lossis ntau dua s bonds.

Lub nplhaib 5 carbon hu ua dab tsi?

Feem ntau nplhaib compounds muaj xws li 5 lub 6 carbon. Cov tebchaw no kuj yog hu ua cyclic. Cyclopentane: Txawm hais tias qhov yooj yim tshaj plaws sawv cev yog hais tias ntawm ib kab kos ntawm ib tug pentagon raws li qhia nyob rau sab laug.
