Propyne is a linear hydrocarbon with 3 carbons and 4 hydrogens.
Two of the carbons are triple bonded, the remaining carbon is single bonded to the middle carbon
Starting at the single bonded end, you have three hydrogens bonded to the first carbon, which is single bonded to the middle carbon. The middle carbon is triple bonded to the last carbon. The last carbon is also bonded to a hydrogen.

It's this one with three lines and CH3 at the end.
It is propyne
A hydrocarbon.
Propylene and propene are synonyms for the same compound with the chemical formula C3H6.If you meant "which is more reactive: propene or propyne", the former being the alkene (contains a double bond) and the latter being the alkyne (contains a triple bond), then propyne should be the more reactive.This is, perhaps, due to the relatively higher steric accessibility of the 4 π(pi)-electrons in propyne (uncited).
both are examples of alkynes and hence have similar chemical properties.
They may be ethene, propene! ethyne, propyne and all the unsaturated hydrocarbons
It is propyne
The 3 in front of the propyne means that the triple bond is between the 3rd and 4th carbon of the longest carbon chain in the molecule. However, you only have 3 carbons in a chain.
Propyne is not called 1-propyne because the prefix "1-" is used to indicate the location of a functional group on a carbon chain when there are multiple sites of attachment. In the case of propyne, there is only one carbon in the chain, so no numbering is needed.

there are 2 pi bonds and 1 sigma bond in propyne (alkynes)
A hydrocarbon.
The chemical formula of propyne is CH3C≡CH.

Three carbon atoms can be arranged in a triangle (cyclopropane), an approximately 109 degree angle (propane), a 120 degree angle (propene), or linearly (propyne).
