- The unsaturation number or degree of unsaturation (U) can be used to determine the number of rings and multiple bonds in a compound from its molecular formula. Given a structure, you can determine the number of hydrogens without having to count them explicitly. Consider three compounds and their degree of unsaturation.

O sp³ hybridized O sp³d hybridized sp² hybridized O sp hybridized N H Divinylamine Justify your answer. The lone pair is a part of the TT system in the second compound. Therefore the compound is conjugated ✓ .As such, the compound absorbs light above 200 nm (UV light). In contrast, 1,4-pentadiene has two double bonds and therefore does not absorb UV light in the region between 200 and 400 nm. 3 isolated cumulated conjugatedarrow_forward
