💡 Solution & Explanation

Correct option: \(\text{C}\). The structure and properties of aromatic hydrocarbons arise from delocalised \(\pi\)-electrons, equalised bond lengths and resonance stabilisation. Recovered question text: 43. CH can be prepared by the reaction of H O with: 4 2 (a) Mg C (b) CaC (c) Be C (d) Al C 2 3 2 2 4 3 COMPREHENSION TYPE Passage # 1 An alkane (A) molecular formula C H reacts with chlorine in the presence of ultra violet light to yield 6 14 three isomeric monochloro derivatives (B) , (C) and (D) . Of these only (C) and (D) undergo dehydrohalogenation with sodium ethoxide in ethanol to produce an alkene . Moreover (
