Question

The degree of unsaturation (double bond equivalent) for a compound with molecular formula C14H12O2 is ________

Answer 1

Answer:

Explanation:

Degrees of unsaturation is equal to 2, or half the number of hydrogens the molecule needs to be classified as saturated. Hence, the DoB formula divides by 2. The formula subtracts the number of X's because a halogen (X) replaces a hydrogen in a compound

The formula for degree of unsaturation is:

where ni is the number of atoms with valence vi.[2]

That is, an atom that has a valence of x contributes a total of x − 2 to the degree of unsaturation. The result is then halved and increased by 1.
