MaAlkenes neAlkynes: Zvimiro uye Mashandisirwo Muhupenyu Hwezuva Nezuva
MaAlkenes nemaalkynes mapoka maviri emahydrocarbon asina kuguta anowanzo kuwanikwa mumakemikari eorganic. Ose ane hunhu hwakasiyana hunoasiyanisa nemahydrocarbon akazara semaalkanes. Muchinyorwa chino, tichakurukura tsananguro dzawo, maumbirwo awo, hunhu hwemuviri nehwemakemikari, uye mashandisirwo awo muhupenyu hwezuva nezuva.
Tsanangudzo yeAlkenes neAlkynes
MaAlkenes mahydrocarbon asina kuguta ane ma bond maviri pakati pemaatomu ekabhoni. Fomura yakajairika yemaalkenes ndeiyi \(C_nH_{2n}\), apo \(n\) iri nhamba yemaatomu ekabhoni. Semuenzaniso, ethene (\(C_2H_4\)) ndiyo alkene iri nyore, ichiteverwa nepropene (\(C_3H_6\)) uye butene (\(C_4H_8\)).
Kune rumwe rutivi, maAlkynes mahydrocarbon asina kuguta ane zvisungo zvitatu pakati pemaatomu ekabhoni. Fomura yavo yakajairika ndeye \(C_nH_{2n-2}\). Mienzaniso yakajairika ndeye ethyne (\(C_2H_2\)) uye propyne (\(C_3H_4\)).
Maumbirwo eMolekyu
Panyaya yemaumbirwo, maalkenes nemaalkynes ane magadzirirwo akasiyana zvichienzaniswa nemaalkanes.
MaAlkenes:
1. Geometry: MaAlkenes ane chimiro chetrigonal planar geometry chakakomberedza maatomu ekabhoni anobatanidzwa mudouble bond. Izvi zvinodaro nekuti double bond ine sigma bond imwe (\(\sigma\)) uye pi bond imwe (\(\pi\)). Pi bond inoita kuti maerekitironi akwezvwe zvakanyanya kumaatomu ekabhoni, zvichikonzera chimiro chakasimba chisingakwanise kutenderera sealkanes.
2. MaIsomers: Kuvapo kwemabond maviri kunobvumira kuumbwa kwemaisomers ejometri, akadai secis ne trans isomers.
MaAlkynes:
1. Geometry: MaAlkynes ane geometry yakatenderedza atomu yekabhoni iri mu triple bond. Triple bond ine sigma bond imwe chete uye pi bonds mbiri, zvichikonzera molecule yakatenderedza zvakanyanya.
2. MaIsomers: MaAlkynes ane maisomers ekuvaka chete nekuti rutsigiro rwemutsara rwechisungo chetatu harubvumiri kuti geometric isomerization ishande.
Zvimiro zveMuviri neMakemikoro
Zvimiro zvemuviri:
1. Mapoka ese ari maviri ane poindi shoma dzekufashaira nekunyunguduka zvichienzaniswa nema alkanes ane molecular mass yakafanana.
2. MaAlkenes nemaAlkynes epasi (C_2 kusvika C_4) anowanzova magasi ari patembiricha yemumba, nepo akakwirira ari madhiri kana zvinhu zvakasimba.
3. Mapoka ese ari maviri anowanzo nyungudika mumvura asi anonyungudika muzvinhu zvinonyungudika zvakaita se ether ne benzene.
Zvimiro zveMakemikari:
1. Kuchinja-chinja: Maalkenes nemaalkynes ese ari maviri anokanganisa mashandiro emuviri nekuda kwekuvapo kwemabond maviri nematatu, zvinoreva kuti maerekitironi anobatanidzwa mumabond aya anotamiswa kana kurwiswa zviri nyore nema reagents emakemikari.
2. Kuwedzera: Chimwe chezvinhu zvinowanzo itika ndeye kuwedzera. MaAlkenes nemaalkynes anogona kuwedzera mamorekuru madiki akadai seH_2, halogens (Cl_2, Br_2), uye halogen acids (HCl, HBr) kune mabhondi avo maviri.
3. Kuumbwa kwePolymerization: MaAlkenes anogonawo kuita polymerization reactions, achigadzira mapolymer anoshandiswa zvakanyanya muindasitiri yepurasitiki.
Mashandisirwo muHupenyu hweZuva Nezuva
MaAlkenes:
1. Polymerization: Imwe yenzira huru dzekushandisa maalkenes ndeyekugadzira mapurasitiki kuburikidza ne polymerization process. Semuenzaniso, ethene (kana ethylene) inoshandiswa kugadzira polyethylene, imwe yemapurasitiki anonyanya kushandiswa mumabhegi epurasitiki, mabhodhoro, nezvimwe zvinhu zvemumba.
2. Indasitiri yeMakemikoro: MaAlkenes anowanzo shandiswa sezvinhu zvekugadzira muindasitiri yemakemikari pakugadzira mishonga yakasiyana-siyana. Semuenzaniso, ethene inoshandiswa kugadzira ethanol, styrene, uye ethylene glycol.
MaAlkynes:
1. Acetylene: Ethyne (acetylene) ndeimwe yealkynes dzinokosha uye dzinoshandiswa zvakanyanya muindasitiri. Acetylene inoshandiswa semafuta mukunamira nekucheka simbi nekuti inogona kuburitsa moto unopisa zvikuru.
2. Kugadzirwa kweOrganic: MaAlkynes anoshandiswawo sematombo ekukwira mukugadzirwa kweorganic kwakaoma. Boka realkyne rinowanzo shandiswa senzvimbo yekubatanidza mapoka akasiyana-siyana anoshanda kumamorekuru makuru eorganic.
Huturu uye Kukanganisa Kwakatipoteredza
Pasinei nemabhenefiti akawanda, kushandiswa kwealkenes nealkynes kunewo njodzi.
1. Huturu: Mamwe ma alkenes nema alkynes anogona kuva nehuturu kana akafemerwa zvakanyanya. Kugara kwenguva refu kunogona kukonzera kutsamwa kunzira yekufema neganda.
2. Nzvimbo: Kurasa zvinhu zvakagadzirwa nealkene zvisina kunaka (senge mapurasitiki) kunogona kukonzera kusvibiswa kwakanyanya kwenharaunda. Saka, kudzokorodza marara uye kugadzirisa marara kwakakosha zvikuru.
Penutup
MaAlkenes nemaalkynes mapoka maviri emahydrocarbon anoita basa rakakosha mukushandiswa kwemakemikari nemaindasitiri. Kunzwisisa chimiro chavo, hunhu hwavo, uye mashandisirwo avo kunogona kutibatsira kushandisa kugona kwavo zvinobudirira uye zvine mutoro. Kunyange zvazvo vachiri nenjodzi dzakati wandei, nehunyanzvi hwakakodzera uye maitiro, mabhenefiti avo anopfuura chero mhedzisiro yakaipa inogona kuitika. Nokudaro, ruzivo rwemaalkenes nemaalkynes rwakakosha pakuvandudza kushandiswa kwavo muhupenyu hwezuva nezuva.
