alkane
homologous series
C3H8 (propane)
C4H10 (butane)
C2H6 (ethane)
C5H12 (pantane)
CH4 (methane)
C6H14 (hexane)
C7H16 (heptane)
C8H18 (octane)
C9H20 (nonane)
C10H22 (decane)
characteristics of homologous series
same fuctional group
same emperical formula
same general formula
each member differ from other by addition of CH2
all characters can be prepared by same general formula
same physical properties
MP and BP increase
density increase
shows two reactions
combustion
substitution
saturated hydrocarbons containing c-c single covalent bond.(sigma bond)
less reactive because it can't easily broken
GENERAL FORMULA: CNH2N+2
ISOMERS: two compounds having same molecular formula but different structures
