Question

question 16
the following molecule has how many degrees of unsaturation?
o 4
o 6
o 0
o 5
o 3

Explanation:

Step1: Identify types of unsaturation

Double - bonds count as 1 degree of unsaturation each, rings count as 1 degree of unsaturation each, and triple - bonds count as 2 degrees of unsaturation each.

Step2: Count double - bonds

There are 2 double - bonds in the molecule.

Step3: Count rings

There are 2 rings in the molecule.

Step4: Count carbon - oxygen double - bond

There is 1 C=O double - bond.

Step5: Calculate degrees of unsaturation

Sum up the contributions: \(2 + 2+1=5\).

Answer:

5
