same molecular formula or structure but their atoms are arranged differently

tetratogenic which caused phocomelia

sedative effects and for managing morning sickness

two most important natural sources of alkanes

complex liquid mixture of organic compounds (alkanes or cycloalkanes)

often found asssociated with petroleum deposits, consists mainly of methane with 80% and ethane with about 5-10%

major constituent of liquefied petroleum gas, a domestic fuel

gas choice in some areas

why alkanes are insoluble in water?

C1-C4

C5-C17

> C18

at room temperature, alkanes occur as

often constitute the parts of the protective coating on leaves and fruits

C27H56 and C29H50

C31H64

C29H50

all of the bonds in alkanes are

alkanes are relatively

alkanes ordinarily do not react with most common acids, bases or oxidizing and reducing agents

alkanes can be used as solvents for extraction or crystallization as well as for carrying out chemical reactions of other substance because of its?

alkanes do not react with some reagents such as

addition of O, removal of H, replacement of C-H bonds by C-O bonds

one or more hydrogen atoms of the alkanes are replaced by halogen atoms
