A distinctive feature of polyphenolics is the possession of biological properties such as antioxidant and antimicrobial activities. Simple synthesis and study about such important class of compounds and their analogs are very important to enhance the understanding of their role in human health and diseases. Accordingly, a series of chalcones (2a-f) have been synthesized by Claisen-Schmidt condensation reaction with required acetophenones and aromatic aldehydes in high yields. The conversion of chalcones to the corresponding flavones (1a-g) taking minimal amount of dimethyl sulfoxide with iodine in presence of sulfuric acid was carried out under microwave conditions in high yields.

The rising concerns regarding mental health arising from the challenges due to pandemics emerged and it’s negative effects on academic performance. Stress and depression levels affected students’ mental well-being as well as academic performance. Surprisingly, this study revealed that the anxiety level of this young generation due to COVID-19 does not influence their activities rather students to have a strong mental capacity to maintain adverse situations. The most possible reason could be their belief that the impact of coronavirus is very low among the young generation. Therefore, they are not anxious about the coronavirus during the pandemic. Rather, they are having depression and stress due to the absence of a proper educational environment.
