Nyob rau hauv kev tshuaj xyuas ntawm cov mis molecular ntawm cov organic molecules, cov degree ntawm unsaturation yog ib tug xam uas txiav txim siab tag nrho cov rings thiab π bonds. Cov mis yog siv hauv cov organic chemistry los pab kos cov qauv tshuaj.
Koj pom qhov ntsuas qhov tsis txaus ntseeg li cas?
Xaiv The Degree of Unsaturation (DU) [2C+2=(2x3)+2=8.] Cov compound xav tau 4 ntau hydrogens txhawm rau kom txaus siab (xav tau tus naj npawb ntawm hydrogens-saib tus naj npawb ntawm hydrogens=8-4=4). Degree ntawm unsaturation yog sib npaug rau 2, los yog ib nrab ntawm cov hydrogens lub molecule yuav tsum tau muab cais raws li saturated.
Dab tsi yog qib ntawm unsaturation hauv organic chemistry?
Nyob rau hauv kev tshuaj xyuas ntawm cov mis molecular ntawm cov organic molecules, qhov degree ntawm unsaturation (tseem hu ua qhov ntsuas ntawm hydrogen deficiency (IHD), ob daim ntawv cog lus sib npaug, lossis qhov ntsuas tsis txaus ntseeg) yog kev suav tias txiav txim siab tag nrho cov nplhaib thiab π daim ntawv cog lus. …
degree ntawm unsaturation ntawm 4 txhais li cas?
Piv txwv: Benzene (4 Degrees Of Unsaturation)
Piv txwv li, yog li cov mis molecular C6H 6 (4 degrees ntawm unsaturation) yog txaus siab los ntawm molecules nrog. 4pi ua. 3 daim ntawv cog lus thiab ib lub nplhaib (benzene) ob daim ntawv cog lus pi thiab ob lub nplhaib (qhov tsis ruaj tsis khov Dewar Benzene, ua ke rau xyoo 1963)
degree ntawm unsaturation ntawm 1/2 txhais li cas?
Ib degree ntawm unsaturation yog sib npaug rau 1 nplhaib los yog 1 ob daim ntawv cog lus (1 π daim ntawv cog lus). Ob qib ntawm unsaturation yog sib npaug rau 2 ob daim ntawv cog lus, 1 lub nplhaib thiab 1 ob daim ntawv cog lus, 2 lub nplhaib, los yog 1 daim ntawv cog lus triple (2 π bonds).
