In this paper, for finite dimensional, basic, and connected algebras over a field, we give a sufficient condition, related to 2-cocycles, for Hochschild extension algebras to be symmetric. Moreover, we define the normalized 2-cocycle associated with a complete set of primitive orthogonal idempotents, and we show that for every 2-cocycle there exists a normalized 2-cocycle such that their cohomology classes coincide.
