Task C2 is a classification task in the context of the Common European Framework of Reference for Languages (CEFR). It involves assessing a learner's ability to understand and produce written texts in the target language. The task requires the learner to demonstrate their comprehension and production skills by completing various written exercises, such as filling in the gaps in a text, completing sentences, or writing short essays. The assessment is based on the learner's ability to use appropriate vocabulary, grammar, and discourse structures at the C2 proficiency level, which is the highest level of language proficiency in the CEFR. **

C reacts alone without forming C2 because the formation of C2 would require a significant amount of energy. The bond dissociation energy of C-C is high, making it difficult for C atoms to form a stable C2 molecule. Additionally, the formation of C2 would require the breaking of strong C-C bonds and the formation of weaker C-C bonds, which is energetically unfavorable. Therefore, C atoms are more likely to react alone rather than form C2. **
