Unsaturated hydrocarbons yog hydrocarbons uas muaj ob lossis triple covalent bonds ntawm cov atoms uas nyob ib sab. Configuration ntawm ib tsis saturated carbons muaj xws li cov saw ncaj, xws li alkenes thiab alkynes, nrog rau cov saw caj dab thiab cov tshuaj tsw qab.

Xav txog qhov no, dab tsi yog qhov piv txwv ntawm unsaturated hydrocarbon?

Ethene, C₂H₄, yog ib piv txwv ntawm unsaturated hydrocarbon . Lwm yam piv txwv ntawm tsis saturated Cov tshuaj yog benzene, C₆H₆, thiab acetic acid, C₂H₄O₂. Txhua lub kaum sab xis ntawm cov pa roj carbon ob daim ntawv cog lus yog 120^o. Tag nrho cov atoms sib koom ua ke rau ob qho kev sib koom ua ke carbon atoms nyob hauv tib lub dav hlau.

Ib yam li ntawd, homologous series twg yog unsaturated hydrocarbons? Alkenes

Tom qab ntawd, dab tsi yog unsaturated hydrocarbons piav txog hom unsaturated hydrocarbons?

Muaj peb hom unsaturated hydrocarbons : alkenes , alkynes thiab aromatic hydrocarbons . Alkenes muaj ib lossis ntau dua carbon-carbon ob daim ntawv cog lus. Alkynes muaj ib lossis ntau dua carbon-carbon triple daim ntawv cog lus, thiab muaj ntxhiab tsw hydrocarbons muaj lub nplhaib benzene los yog aromatic hauv lawv cov qauv.

Yuav ua li cas koj thiaj paub tias hydrocarbon yog unsaturated?

Unsaturation qhia tau hais tias qee qhov carbon-hydrogen bonds tau poob los ntawm pi bonds ntawm carbon atoms. Muaj tsawg dua tus lej siab tshaj os hydrogens txheeb ze rau cov pa roj carbon atoms. 2. Unsaturated hydrocarbons muaj ib lossis ntau dua ob lossis peb daim ntawv cog lus ntawm carbon atoms.
