Concept explainers
(a)
Interpretation:
Better nucleophile in methanol is to be identified from the given options.
Concept Introduction:
Stronger the base, better is the nucleophile.
If the attacking atoms are different in size and the reaction is carried out in a protic solvent, stronger the bases are poorer nucleophiles as ion-dipole interactions between the ions and the solvent.
(b)
Interpretation:
Better leaving group is to be identified.
Concept Introduction:
Weaker the basicity of the group better is the leaving propensity.
If the attacking atoms are different in size and the reaction is carried out in a protic solvent, stronger the bases are poorer nucleophiles as ion-dipole interactions between the ions and the solvent.
(c)
Interpretation:
Better leaving group is to be identified.
Concept Introduction:
Weaker the basicity of the group better is the leaving propensity.
If the attacking atoms are different in size and the reaction is carried out in a protic solvent, stronger the bases are poorer nucleophiles as ion-dipole interactions between the ions and the solvent.
(d)
Interpretation:
Better leaving group is to be identified.
Concept Introduction:
Weaker the basicity of the group better is the leaving propensity.
If the attacking atoms are different in size and the reaction is carried out in a protic solvent, stronger the bases are poorer nucleophiles as ion-dipole interactions between the ions and the solvent.
(e)
Interpretation:
Better leaving group is to be identified.
Concept Introduction:
Weaker the basicity of the group better is the leaving propensity.
If the attacking atoms are different in size and the reaction is carried out in a protic solvent, stronger the bases are poorer nucleophiles as ion-dipole interactions between the ions and the solvent.
(f)
Interpretation:
Better leaving group is to be identified.
Concept Introduction:
Weaker the basicity of the group better is the leaving propensity.
If the attacking atoms are different in size and the reaction is carried out in a protic solvent, stronger the bases are poorer nucleophiles as ion-dipole interactions between the ions and the solvent.
