Question

23 multiple choice 2 points the synthetic steroid ru - 486 is shown below. how many pi bonds does ru - 486 contain? (ch₃)₂n o 2 o 10 o 8 o 4 previous

Explanation:

Step1: Identify double - bond pi bonds

Each carbon - carbon double bond ($C = C$) has 1 pi bond. There are 4 such double bonds in the structure.

Step2: Identify triple - bond pi bonds

Each carbon - carbon triple bond ($C\equiv C$) has 2 pi bonds. There is 1 such triple bond in the structure which contributes 2 pi bonds.

Step3: Identify $C = O$ pi bonds

The carbon - oxygen double bond ($C = O$) has 1 pi bond. There is 1 such bond in the structure contributing 1 pi bond.

Step4: Count total pi bonds

Sum up the pi bonds: $(4\times1)+(1\times2)+(1\times1)=4 + 2+1=10$.

Answer:

10
