In chemistry we are learning about thermochemistry. We are learn about heat of formation.
Acetylene(gas) has a low value for heat of formation
+ 226.6 KJ/mol
my teacher tells me that is has a lot of potential energy? but how? is it because it is endothermic? if so why would it do that?

The reason acetylene has lots of potential energy is because its triple bond between its carbons stores the energy. It takes a lot of energy to create that triple bond, so when it is broken a lot of energy is released.
Any single molecule cannot be endothermic or exothermic. Those terms are used to describe a reaction.
Good Luck!

*Why does acetylene HAVE a lot of potential energy.
*We are learning about the heat of formation.
This sounds like it is YOUR homework! Find out for yourself.
