Assertion : Carbanions like ammonia have pyramidal shape. Reason : The carbon atom carrying negative charge has an octet of electrons.
Assertion : The carbocation CF CH is less stable than CF . Reason : In case of CF CH ,CF is strong electron withdrawing, therefore increases +ve charge whereas in CF , lone pair of ‘F’ overlap with vacant p-orbi…
Assertion: A compound with delocalised electrons is more stable than that compound would be if all its electrons were localised. Reason: The extra stability, a compound gains as a result of having delocalised electro…
Assertion : Tropylium cation is aromatic in nature. Reason :The only property that determines its aromatic behaviour is planar structure.
Assertion: Tropylium cation is more stable than Reason: It is stabilized by both resonance effect and inductive effect.
Assertion: NF is a weaker ligand than N CH . Reason: NF ionizes to give Fions in aqueous solution.
