The electronic formulas for methane ethane, and propane are easily written Although the electronic formula representation makes the molecules seem planar, it must be remembered that in all the alkanes the c-c and c-h bonds have the geometrical arrangement set b the tetrahedral configuration of each carbon unI
The electronic formulas for methane, ethane, and propane are easily written. Although the electronic formula representation makes the molecules seem planar, it must be remembered that in all the alkanes the C—C and C—H bonds have the geometrical arrangement set by the tetrahedral configuration of each carbon unit

There are two hydrocarbons having the formula 4H10, and these are known as normal butane and isobutane. The two butanes are isomers. They have the same empirical formula, and hence the same composition, but different physical and chemical properties, because they differ in the arrangement of the atoms in their molecules. normal butane. n butane, is astraight chain?molecule and isobutane isa“ branched chain” molecule. The number of possible isomers increases with increasing molecular weight; the hydrocarbon of large molecular weight have great numbers of isomers

They have the same empirical formula, and hence the same composition, but different physical and chemical properties, because they differ in the arrangement of the atoms in their molecules. Normal butane, nbutane, is a “straight chain” molecule and isobutane is a “branched chain” molecule. The number of possible isomers increases with increasing molecular weight; the hydrocarbon of large molecular weight have great numbers of isomers
