Cyclooctatetraene reacts with potassium metal to form the stable cyclooctatetraene dianion, C 6 H 8 2- . Whether the reaction will take place readily or not is to be stated. The geometry expected for the cyclooctatetraene dianion is also to be given. Concept introduction: According to Huckel’s Rule a planar, cyclic conjugated system will be aromatic if it contains (4n+2)Ï€ electrons. Systems with 4nÏ€ electrons will be antiaromatic. If the product is more stable than the reactant the reaction will proceed readily. A planar geometry is expected for ions that are aromatic. To state: Whether the reaction in which cyclooctatetraene reacts with potassium metal to form the stable cyclooctatetraene dianion, C 6 H 8 2- will take place readily or not. To give: The geometry expected for the cyclooctatetraene dianion.

Laser. Indicate the relationship between metastable state and stimulated emission.

Answer 1

Question

Definition Definition Rule that estimates whether a given organic planar ring structure will show an aromatic property. A cyclic ring molecule is said to follow Hückel’s rule if the л-electrons count in a molecule is [4n+2], where n stands for a positive numerical value. It is also called the [4n+2] rule. Hückel's rule, sometimes referred to as the aromaticity rule, is one but not the only criteria to judge a molecule for aromaticity.
