Practice question · Numerical answer
A carbon-carbon triple bond is drawn between two atoms. How many of its three bonds are pi bonds?
Hints
- The first bond between any two atoms is always the sigma bond.
- Three bonds in total, of which exactly one is sigma.
Show the answer
2
Why
The first bond formed between two atoms is always sigma; every additional one is pi. A triple bond is therefore one sigma and two pi bonds.
