What is the index of hydrogen deficiency in C₂₀H₃₆?

Question

Quizplus · Accepted Answer

The index of hydrogen deficiency (IHD) can be calculated using the formula, IHD = [(2n + 2) - (h + x)]/2 Where, n is the number of carbons, h is the number of hydrogens, and x is the number of halogens (Fluorine, Chlorine, Bromine, Iodine). C₂₀H₃₆ has 15 carbons (n=15), 1 Fluorine (x=1) and a total of 22 hydrogens (h=22). IHD = [(2*15 + 2) - (22 + 1)]/2 IHD = 29/2 IHD = 14.5 Since IHD is not a whole number, we round it off to the nearest whole number, which is 3. Therefore, the answer is C.
