Alkenes muaj ntau dua li lawv cov alkanes cuam tshuam vim qhov txheeb ze tsis ruaj khov ntawm ob daim ntawv cog lus. Lawv feem ntau yuav koom nrog ntau yam kev cuam tshuam, suav nrog kev sib txuas, sib ntxiv, hydrogenation, thiab halogenation cov tshuaj tiv thaiv.

Dab tsi ua rau alkenes ntau dua alkanes?

Tus naj npawb ntawm hydrogen atoms hauv ib qho alkene yog ob npaug ntawm cov pa roj carbon atoms, yog li lawv muaj cov qauv dav dav. Alkenes yog unsaturated, txhais tau tias lawv muaj ob daim ntawv cog lus. Daim ntawv cog lus no yog vim li cas cov alkenes muaj zog dua li cov alkanes.

Puas alkenes muaj zog dua alkanes?

Alkenes yog tsev neeg ntawm hydrocarbons (cov tshuaj muaj cov pa roj carbon thiab hydrogen nkaus xwb) uas muaj cov pa roj carbon ob daim ntawv cog lus. Alkenes yog cov sib txuas ruaj khov, tab sis reactive dua alkanes vim yog cov reactivity ntawm carbon-carbon π-bond.

Dab tsi yog qhov txawv ntawm alkanes thiab alkenes?

Cov alkanes yog cov hydrocarbons saturated-uas yog, hydrocarbons uas tsuas muaj ib daim ntawv cog lus xwb. Alkenes muaj ib lossis ntau dua carbon-carbon ob daim ntawv cog lus.

Yuav ua li cas yog cov reactive alkanes alkenes los yog alkynes?

1) Hauv cov tshuaj tiv thaiv acid-puag, alkynes yog cov reactive tshaj plaws ua raws li alkenes thiab alkanes. Qhov no yog vim kev ruaj ntseg ntawm conjugate puag ntawm alkyne los ntawm sp hybridized carbon atom. 2) Hauv electrophilic hloov pauv, alkynes yogtsawg reactive dua alkenes.

Vim li cas toluene reactive dua li benzene?

Vim li cas toluene reactive dua li benzene?

Toluene thiab Phenol muaj ntau reactive dua benzene vim lawv pab pawg ntxiv electron ceev rau lub nplhaib . Toluene's methyl pawg ntxiv cov electron ceev los ntawm cov nyhuv inductive inductive hauv chemistry, cov nyhuv inductive yogib qho cuam tshuam txog kev sib kis ntawm kev sib koom tsis sib xws ntawm kev sib koom ua ke ntawm cov khoom siv hluav taws xob los ntawm cov saw hlau ntawm atoms hauv cov molecule, ua rau ib tug mus tas li dipole nyob rau hauv ib daim ntawv cog l

Vim li cas imines ntau dua reactive dua aldehydes?

Vim li cas imines ntau dua reactive dua aldehydes?

Txawm li cas los xij, yog tias cov tshuaj tiv thaiv tau khiav hauv cov kua qaub me me, vim tias cov imine nitrogen yog qhov yooj yim dua li carbonyl oxygen, ntau dua ntawm imine nitrogen yuav protonated dua carbonyl oxygen. Qhov no yuav ua rau cov protonated imine carbon ntau ntau electrophilic (positively polarized).

Vim li cas anhydrides ntau dua reactive dua amides?

Vim li cas anhydrides ntau dua reactive dua amides?

Amides yog qhov ruaj khov tshaj plaws, thiab qhov tsis zoo tshaj plaws, vim tias nitrogen yog ib qho muaj txiaj ntsig pub dawb ntawm electrons rau pawg carbonyl. Anhydrides thiab esters tsis ruaj khov me ntsis, vim tias cov pa oxygen ntau dua electronegative dua nitrogen thiab yog qhov tsis zoo ntawm cov khoom siv hluav taws xob.

Vim li cas alkynes ruaj khov dua alkenes?

Vim li cas alkynes ruaj khov dua alkenes?

Nws vim electrons ntawm ntau daim ntawv cog lus carbon-carbon tau nthuav tawm ntau dua thiab tsis ruaj khov. … Cov txheeb ze sib raug zoo ntawm ntau cov pa roj carbon-carbon daim ntawv cog lus xws li peb alkyne thiab alkanes yog me dua li ib daim ntawv cog lus ntawm ib qho alkene yog li ua rau nws tsis ruaj khov thiab rov ua haujlwm.

Vim li cas tertiary alkanes thiaj li muaj zog dua?

Vim li cas tertiary alkanes thiaj li muaj zog dua?

Tertiary carbocations yog ruaj khov los ntawm cov nyhuv inductive inductive hauv chemistry, cov nyhuv inductive yog ib qho cuam tshuam txog kev sib kis ntawm kev sib koom tsis sib xws ntawm kev sib koom ua ke ntawm kev sib txuas ntawm cov hluav taws xob los ntawm cov saw hlau ntawm atoms hauv cov molecule, ua rau lub dipole mus tas li hauv daim ntawv cog lus.
