Question

How many sigma and pi bonds are present in ch2=ch-ch=ch2?

Answer 1

Answer:

There are seven sigma bonds and three pi bonds in CH2=CH-CH=CH2.

From left till right the carbons are one, two, three, and four: 3H are attached to 1C, so there are three sigma bonds.

In C2 one sigma bond and one pi bond are present.

Answer 2

There are nine sigma and two pi bonds are present.

• In the above compound, four sigma bonds are present between the four carbon atoms.
• Five sigma bonds are present between the carbon and hydrogen atoms.
• In this compound, two pi bonds are present between the two carbon atoms.
• In total there are nine sigma and two pi bonds are present.
