Ring substitution in aromatic ethers
Alkoxy group is ortho and para directing and it directs the incoming groups to ortho and para position. It becomes the aromatic ring leads to electrophilic substitution reaction.
III, IV and V points out high electron density at ortho and para position.

The standard free energy change for a reaction is -212.3 kJ mol -1 . If the enthalpy of the reaction is - 216.7 kJ mol -1 , calculate the entropy change for the reaction.
Explain enantiomer The two structures differ in configuration at both asymmetric carbons. They are enantiomers.
