The observation that the β- diketone represented by the model has no detectable enol content and it is as acidic as acetone is to be explained. Concept introduction: The hydrogen atoms attached to the carbon flanked by two carbonyl groups can be easily removed as protons. Hence the β- diketones are acidic and form enolates which can be stabilized by resonance. The formation of double bonds at the bridge head position is not possible as the molecule will be highly strained.

Question

Explain how, based on physical gas adsorption isotherms, we can determine whether multi-walled C nanotubes are open at their ends. Explain this.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
