Question

For the following formula, CHoNBr, calculate the IHD and select all the types of unsaturation that might be present in the molecule based on the IHD. Number HD2 The types of unsaturation that might be present: O no unsaturation; no multiple bonds or ring closings O one double bond or one ring closing three double bonds; or three ring closings; or two double bonds and one ring closing; or one double bond and two ring closings; or one triple bond and one double bond; or one triple bond and one ring closing O @r many possibilities; most likely a benzene ring ial In& View Solution Check Answer e Next Exit ....-0

Explanation / Answer

Let

CcHhNnOoXx,;

then we can obtain:

IHD = 0.5 * [2c+2-h-x+n]

identify

c = 7, h =10; n = 1, Br = 1

IHD = 0.5 * (2*7+2-10-1+1)

IHD = 3

therefore, this is is most likely a benzene, choose D
