Group 14 : Important trends and anomalous behavior of Carbon

The video explores the unique properties of carbon, highlighting its differences from other group elements due to its smaller atomic size, higher electronegativity, and absence of d orbitals. It discusses carbon's ability to form multiple bonds and its tendency for catenation. The video delves into carbon's allotropic forms, including diamond, graphite, and fullerenes, explaining their structures and uses. It also covers impure forms like coke, charcoal, and carbon black, and their applications in various industries.
