Detailed explanation-1: -Hydrocarbons having at least one triple bond between two carbon atoms are known as alkyne . General formula of alkyne is CnH2n−2.
Detailed explanation-2: -CnH2n+2 is the standard formula for alkanes. These are called saturated hydrocarbons. It means all carbon atoms are bonded to the maximum amount of hydrogen atoms possible, i.e. saturated with hydrogen. CnH2n is the standard formula for alkenes.
Detailed explanation-3: -Alkanes have the general formula of CnH2n+2 where n is the number of carbon atoms.
Detailed explanation-4: -An alkane is a compound whose chemical formula follows the formula CnH2n+2 C n H 2 n + 2 where n is the number of carbons. In the structure above, the carbons of the given compounds are marked by green dots. Thus, n = 8.
