# How would you draw a structure containing only carbon and hydrogen that is a chiral alkyne with six carbon atoms?

Apr 16, 2016

You need to draw chiral centre while maintaining a formula of ${C}_{6} {H}_{10}$.

#### Explanation:

A structure of $H - C \equiv C - C \left(H\right) \left(C {H}_{3}\right) \left(C {H}_{2} C {H}_{2}\right)$ is one possibility (this might be the only possibility). I suppose it could be made from homochiral $X - C \left(H\right) \left(C {H}_{3}\right) \left(C {H}_{2} C {H}_{2}\right)$ and acetylide.

3-methyl-pent-1-yne

#### Explanation:

The given condition

• The compound is chiral alkyne with 6 carbon atom
• So it should contain one carbon atom (central) linked with 4 different grs
• It should have alkynyl gr (say ethynyl - 2 carbon system )
• two alkyl grs ( ethyl - 2carbon system and methyl- 1- carbon system )
• Its 6 carbon atoms satisfied

Satisfying these conditions we get the compound
3-methyl-pent-1-yne The Structure is shown below
