A.Alkynes have a neutral pH.
Molecules don't have a pH. pH is a characteristic of a solution.

B.Alkynes tend to be acidic.
They do have hydrogens that are more acidic than alkenes or alkanes due to the triple bond.

C.Alkynes tend to be soluble in water.
All hydrocarbons are non-polar, and thus not very soluble in water.

D.Alkynes are not combustible
All hydrocarbons are combustible.
