(a)
Interpretation:
The product of the given reaction is has be given.
Concept Introduction:
(b)
Interpretation:
The product of the given reaction is has be given.
Concept Introduction:
Pyridine is more reactive than benzene towards nucleophilic aromatic substitution reactions. Nucleophile adds to the ring carbon attached to the leaving group. Then, the leaving group is eliminated. Substitution takes place at C-2 or C-4 because it leads to the most stable intermediate.
(c)
Interpretation:
The product of the given reaction is has be given.
Concept Introduction:
(d)
Interpretation:
The product of the given reaction is has be given.
Concept Introduction:
Aromatic five-membered heterocyclic compounds undergo electrophilic aromatic substitution reactions preferentially at 2-position. The intermediate obtained by adding a substituent to this position is more stable than the intermediate obtained by adding a substituent to C-3 position.
(e)
Interpretation:
The product of the given reaction is has be given.

(f)
Interpretation:
The product of the given reaction is has be given.
Concept Introduction:
Alkyl halide reacts with amine to form alkyl-substituted product. The reaction mechanism is nucleophilic aliphatic substitution. Amines are generally nucleophilic in nature. Therefore, the reaction easily occurs in mild conditions.
(g)
Interpretation:
The product of the given reaction is has be given.

- Don't used hand raitingarrow_forwardIt is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation. OMe H A G₂ = +0.6 kcal/mol OMe What is unexpected is that the closely related 2-methoxytetrahydropyran prefers the axial conformation: H H OMe OMe A Gp=-0.6 kcal/mol Methoxy: CH3O group Please be specific and clearly write the reason why this is observed. This effect that provides stabilization of the axial OCH 3 group in this molecule is called the anomeric effect.
