    Hydrocarbon:- Jo sirf aur sirf carbon aur hydrogen se bane ho
    Type of hydrocarbon:-
    ->Saturated hydrocarbon:- Alkane e.g. Ch3-ch2-ch2-Ch3
    -> Unsaturated hydrocarbon:- Alkene e.g. Ch2=Ch2(ethene) and Alkyne e.g. Ch=-Ch(ethyne)
    Alkane:- Single bond between C and C.
    -> General formula:- CnH(2n+2)
    -> Difference between two consecutive term is CH2(difference in Mass:-14u)
    E.g:- Ch4
    C2H6
    C3-CH2-CH3(C3H8)
    C4H10
    C5H12
    C6H14
    .
    .
    .
    etc.
    Alkene:- Double bond between C=C
    -> General formula:- CnH(2n)
    -> difference between two consecutive term is CH2.
    e.g. =>Ch2=Ch2(ethene)
    ->Ch3-Ch=Ch2(propene)
    ->Ch3-ch2-ch=Ch2(butene)
    .
    .
    etc.
    Alkyne:- triple bond between C=-C
    ->General formula:- CnH(2n-2)
    -> Difference between two consecutive terms is CH2.
    -> e.g:- C2H2(ethyne)
    C3H4(propyne)
    C4H6(butyne)
    C5H8(pentyne)
    C6H10(hexyne)
    .
    .
    etc.
    समजातीय श्रेणी:- Yadi kisi series me two consecutive terms ke beech ka difference Ch2 ho toh us series ko Samjatiya Series kahte hai.
    e.g. Alkane,Alkene,Alkyne
    -> Samjatiya Series hone se series ke members ki chemical properties equal hoti hai
    Preparation of Alkane:-
    Method(1). By hydrogenation of alkene and alkyne
    Pt/pd/Ni
    Reaction:- Ch2=Ch2 +H2-------> Ch3-Ch3
    ASKC:- ->for nickel(ni) catalyst temp. High hona chahiye
    ->Pd/Pt ke liye room temperature hona chahiye.
