Muenzaniso weMibvunzo yeKukurukurirana yeHydrocarbon Inonhuhwirira
Mahydrocarbon anonhuhwirira iboka remakemikari eorganic ane ring yebenzene sechimiro chawo chepakati. Maumbirwo awo emakemikari anoratidzwa nekuvapo kwezvisungo zviviri zvakagadzikana muring yekabhoni matanhatu. Mukemikari, mahydrocarbon aromatic anowanzo kuve musoro wenyaya uye anoshandiswa zvakanyanya muindasitiri nekutsvaga. Chinyorwa chino chichakurukura mienzaniso yakati wandei yemahydrocarbon aromatic nemhinduro dzawo kusimbisa kunzwisisa pfungwa iyi.
1. Nhanganyaya yeMahydrocarbon Anonhuhwirira
Mahydrocarbon anonhuhwirira, kana kuti maarenes, anozivikanwa nekuvapo kweringi rimwe chete kana anopfuura ebenzene muchimiro chawo. Benzene (C₆H₆), chinhu chiri nyore pane izvi, chine chimiro chakasimba nekuda kwekuchinja kwe maerekitironi epi. Mahydrocarbon anonhuhwirira anowanikwa muzvigadzirwa zvakasiyana-siyana zvekutengeserana, zvinosanganisira mafuta, zvinonyungudutsa, uye mapurasitiki.
Muenzaniso Mubvunzo 1: Kuzivikanwa kweMakemikoro Anonhuhwirira
Mubvunzo:
Zvichienderana neizvi: C₆H₆, C₆H₁₂, C₆H₄Cl₂. Ndeipi yadzo iri hydrocarbon inonhuhwirira?
Kukurukurirana:
– C₆H₆ ibenzene, iyo iri pachena kuti hydrocarbon inonhuhwirira ine ring yebenzene.
– C₆H₁₂ i cyclohexane, inova chinhu chinotenderera asi hachina kunhuhwirira nekuti haina system yekubatanidza mabhondi maviri.
– C₆H₄Cl₂ idichlorobenzene, inova inobva mubenzene ine zvinhu zviviri zvinotsiva chlorine kuitira kuti irambe iine hunhu hwayo hwekunhuhwirira.
Saka, zvinhu zvinonhuhwirira zviri mubvunzo uyu ndiC₆H₆ naC₆H₄Cl₂.
2. Maitiro emakemikari eMahydrocarbon Anonhuhwirira
Muenzaniso 2: Kutsiva Kwechinhu Chinonhuhwirira cheElectrophilic
Mubvunzo:
Benzene inopindura nebromine (Br₂) kana paine FeBr₃ catalyst. Nyora reaction equation wobva watumidza zvigadzirwa zvacho.
Kukurukurirana:
Kugadziriswa kwechinhu chinotsiva aromatic aromatic (SEAr) kunoitika kana benzene ikadyidzana nebromine paine FeBr₃ catalyst. Kugadziriswa uku kunotsiva atomu imwe chete yehydrogen iri pa ring yebenzene neatomu yebromine. Equation yemhinduro ndeiyi:
C₆H₆ + Br₂ → C₆H₅Br + HBr (kana paine FeBr₃)
Chigadzirwa chinobuda ibromobenzene.
Muenzaniso Mubvunzo 3: Kuita kweBenzene Nitration
Mubvunzo:
Nyora equation ye reaction ye nitration ye benzene uye nyora zita rechinhu chakagadzirwa.
Kukurukurirana:
Benzene nitration ndeimwe muenzaniso we electrophilic aromatic substitution reaction umo benzene inosangana nemusanganiswa we nitric acid (HNO₃) uye sulfuric acid (H₂SO₄). Iyo reaction equation ndeiyi:
C₆H₆ + HNO₃ → C₆H₅NO₂ + H₂O (pamberi paH₂SO₄)
Chigadzirwa chinobuda i nitrobenzene.
3. Stereochemistry muMahydrocarbon Anonhuhwirira
Muenzaniso Mubvunzo 4: Hunhu hweMakemikoro eMahydrocarbon Anonhuhwirira
Mubvunzo:
Kurukurai kuti sei benzene isingashande zvakanyanya kana ichienzaniswa nealkenes kunyangwe ese ari maviri aine mabhondi maviri.
Kukurukurirana:
Benzene nealkenes zvese zvine ma bond maviri, asi benzene chinhu chinonhuhwirira chakasimba. Kugadzikana uku kunobva mukubviswa kwema electron epi mukati me ring yebenzene, izvo zvinogadzira hurongwa hwema pi bond akapararira mumorekuru yese uye zvinoita kuti simba rekuwedzera rinodiwa kuti riputse ma bond ari mukati me ring rikure. Kune rumwe rutivi, ma Alkenes anonyanya kushanda nekuti ma double bond avo anowanikwa munzvimbo imwe chete uye ari nyore kuwana kuti awedzere ma reaction.
4. Mashandisirwo eMahydrocarbon Anonhuhwirira
Muenzaniso Mubvunzo 5: Mashandisirwo Emahydrocarbon Anonhuhwirira Mumaindasitiri
Mubvunzo:
Taura mashandisirwo matatu e benzene nemamwe mishonga inonhuhwirira mumaindasitiri.
Kukurukurirana:
1. Kugadzira Mapurasitiki: Benzene chinhu chakakosha pakugadzira polystyrene, iyo inoshandiswa kugadzira marudzi akasiyana-siyana epurasitiki.
2. Zvinonyungudutsa: Mahydrocarbon akawanda anonhuhwirira akadai setoluene nexylene anoshandiswa sezvinonyungudutsa muindasitiri yependi nekupenda nekuda kwehunhu hwawo hwakanaka hwekunyungudutsa.
3. Zvimisikidzo zveMishonga: Mishonga yakawanda ine zvinhu zvinonhuhwirira, semuenzaniso aspirin ine boka rebenzene.
Saka, mahydrocarbon anonhuhwirira anoita basa rakakosha zvikuru mumakemikari emazuva ano nemaindasitiri.
Mhedziso
Kudzidza nezvemahydrocarbon anonhuhwirira kunosanganisira kunzwisisa chimiro, maitiro, uye isomerism zvine chekuita nemakomputa aya. Nekupindura mibvunzo inoshanda iri pamusoro apa, vaverengi vanotarisirwa kuwana kunzwisisa kuri nani kwepfungwa dzakakosha dzine chekuita nemahydrocarbon anonhuhwirira uye mashandisirwo awo. Makomputa aya anoita basa rakakosha muminda yakasiyana-siyana, kubva kumaindasitiri kusvika kutsvagurudzo, zvichiita kuti ave zvinhu zvakakosha pakudzidza kemikari yeorganic.
