Shape of a molecule with 3 bond pairs and one lone pair?
Pyramidal.
1 of 6
Resonance/delocalisation energy
The difference in enthalpy of hydrogenation values for Kekule's benzene and real benzene. It indicates towards the extra stability of the delocalised Pi electron system in actual benzene.
2 of 6
Importance of the nucleophilic addition reactions between aldehydes/ketones and the nucleophile CN-?
The reaction increases the chain length and introduces chirality.
3 of 6
Brady's reagent can be used to identify the specific aldehyde/ketone present by determining the specific melting point of the orange precipitate it forms. What is this process called?
Derivatisation.
4 of 6
Conditions for friedal crafts alkylation of benzene?
