Question

# Propyne molecule contains:

A
6 sigma and 2 pi bonds
B
5 sigma bonds
C
5 pi bonds and 1 sigma bond
D
2 sigma and 3 pi bonds.

Solution

## The correct option is C 6 sigma and 2 pi bondsIt is to be noted that $$\pi$$ bond only form when $$\sigma$$ bond already exist, tripple bond means $$1$$ $$\sigma$$ and $$2$$ $$\pi$$ bond, so propyne has $$6$$ $$\sigma$$ and $$2$$ $$\pi$$ bonds.  So the correct option is $$[A]$$.Chemistry
