# How many sigma and pi bonds are in the following compounds?

Jan 14, 2018

Let us try the problem for allene...${H}_{2} C = C = C {H}_{2}$...which is a real molecule that you could put in a bottle.....

#### Explanation:

Well, we got $4 \times C - H$ $\sigma \text{-bonds}$...

...and $2 \times C - C$ $\sigma \text{-bonds}$...

...and $2 \times C - C$ $\pi \text{-bonds}$...

So that is 8 bonds in total....
