Hidrokaboni ni aina mbalimbali za kampaundi ogania za kikemia zinazojengwa kwa atomi za hidrojeni na kaboni pekee.
Kwa asili zinapatikana hasa katika mafuta ya petroliamu iliyotokana na mchakato wa kuoza kwa mimea na mata ogania yenye kaboni na hidrojeni nyingi. Hidrokaboni haziwezi kuingia katika mmenyuko wa kikemia na maji.
Hidrokaboni ni chanzo muhimu cha nishati kwa binadamu duniani; petroli na diseli ni mchanganyiko wa aina za hidrokaboni.
Vikundi vya hidrokaboni
[hariri | hariri chanzo]Hidrokaboni hupangwa katika vikundi 5.
Alkani
[hariri | hariri chanzo]Alkani ni hidrokaboni za msingi. Fomula yake ni CnH2n+2.
Jina la alkani | Fomula |
---|---|
Methani | CH4 |
Ethani | C2H6 |
Propani | C3H8 |
Butani | C4H10 |
Pentani | C5H12 |
Hexani | C6H14 |
Heptani | C7H16 |
Oktani | C8H18 |
Nonani | C9H20 |
Dekani | C10H22 |
Alkeni
[hariri | hariri chanzo]Alkeni hufanana na alkani lakini zina muungo jozi kati ya kaboni na kaboni. Fomula yake ni CnH2n.
Jina la alkeni | Fomula |
---|---|
Etheni | C2H4 |
Propeni | C3H6 |
Buteni | C4H8 |
Penteni | C5H10 |
Hexeni | C6H12 |

Okteni | C8H16 |
Noneni | C9H18 |
Deseni | C10H20 |
Alkini
[hariri | hariri chanzo]Alkini zina muungo wa mara tatu kati ya kaboni na kaboni. Fomula yake ni CnH2n-2
Jina la alkini | Fomula |
---|---|
Ethini | C2H2 |
Propini | C3H4 |
Butini | C4H6 |

Heptini | C7H12 |
Octini | C8H14 |
Nonini | C9H16 |
Desini | C10H18 |
Sikloalkani
[hariri | hariri chanzo]Sikloalkani ni isomeri za alkeni. Fomula yake ni pia (CnH2n) lakini hazina muungo jozi kati ya kaboni na kaboni.
Jina la Sikloalkani | Fomula |
---|---|
Siklopropani | C3H6 |
Siklobutani | C4H8 |
Siklopentani | C5H10 |
Siklohexani | C6H12 |
Sikloheptani | C7H14 |
Sikloctani | C8H16 |
Siklononani | C9H18 |
Siklodekani | C10H20 |
Alkadini
[hariri | hariri chanzo]Alkadini zina muungo jozi mbili kati ya kaboni na kaboni. Fomula ni CnH2n-2. Hizi ni isomeri za Alkini.
Hidrokaboni aromatiki
[hariri | hariri chanzo]Hidrokaboni aromatiki ni molekuli ogania yenye umbo la mviringo tambarare. Fomula yake ni CnH2n-6 na "n" ni sawa na kubwa kuliko 6.
