The general formula of alkynes is eqC_nH_2_n-2 eq where n is an integer number that corresponds to the number of atoms present in a compound. BY reason of their formula alkanes are said to HAVE NO DEGREES of UNSATURATION Where the formula is C_nH_2n or C_nH_2nO_m each 2 hydrogens LESS than 2n2 represents a degree of unsaturation.
