Question

How many sigma and pi bonds are in an ethyne molecule?

Answer 1

`3` `xx` `sigma` and `2` `xx` `pi`

Explanation:

In the acetylene molecule, `H-C-=C-H`, we can directly count `3` `sigma` bonds, `2xxC-H` and `1xxC-C`. The remaining `2` `pi` bonds lie above and below and beside the `C-C` vector.
