"WebA triple bond counts as two IHD. Hydrocarbons (CxHy): 2x + 2 - y IHD = 2 (where x and y stand for # of C and H respectively.) Example 1: IHD for C2H4 is 2(2) + 2 - 4 = 1 2 This means it can have either one double bond or one ring. It cannot have a triple bond. Since you cannot form a ring with only two C’s, it must have a double bond. " - Ihd of a ring

WebRings and degrees of unsaturation The general formula for cycloalkanes is C n H 2n and even though they only have single bonds, they are still lacking the two extra hydrogens that alkanes have (CnH2n+2). The reason for this is that none of the carbons get to turn into a CH 3 like we have on the periphery of alkanes: http://ursula.chem.yale.edu/~chem220/chem220js/STUDYAIDS/unsaturation/unsat.html
