What do you mean by $Alkane$? Explain the formation of $Alkane$ from $Methane$ $(CH_{4})$,by substituting the hydrogen atoms with a $-CH_{3}$ group.

(N/A) Alkanes are saturated open-chain hydrocarbons containing carbon-carbon single bonds.
$Methane$ $(CH_{4})$ is the first member of this family. If you replace one hydrogen atom of $Methane$ with a $-CH_{3}$ group,the resulting hydrocarbon is $Ethane$ $(C_{2}H_{6})$.
By continuing this process of replacing a hydrogen atom with a $-CH_{3}$ group,we can derive higher alkanes. For example,replacing a hydrogen in $Ethane$ leads to $Propane$ $(C_{3}H_{8})$,and further substitution leads to $Butane$ $(C_{4}H_{10})$ and its isomers like $Isobutane$.
