When a benzene ring is attached to an alkane with a functional group, it is considered as substituent instead of a parent

Position isomerism is due to the difference in the position of a functional group, multiple bond or substituent in the same carbon chain

In benzene diazonium chloride, the functional group is

Explain the fact that in aryl alkyl ethers (i) the alkoxy group activates the benzene ring towards electrophilic substitution and (ii) it directs the incoming substituents to ortho and para positions in benzene ring.

When an electron withdrawing or electron releasing group is attached to carbon chain, polarity is induced on the carbon atom and on the substituent attach to it. This permanent polarity is due electron displacement due to difference in electronegativities this is called inductive effect or I effect. The inducitve effect depends in the electronegativity of the substituent. The inductive effect is broadly classified as (i) negative inductive effect or -I effect. (ii) positive inductive effect or +I effect. The group which exhibits the maximum -I effect

When an electron withdrawing or electron releasing group is attached to carbon chain, polarity is induced on the carbon atom and on the substituent attach to it. This permanent polarity is due electron displacement due to difference in electronegativities this is called inductive effect or I effect. The inducitve effect depends in the electronegativity of the substituent. The inductive effect is broadly classified as (i) negative inductive effect or -I effect. (ii) positive inductive effect or +I effect. Which of the following statements is correct about inductive effect ?

The inducitve effect depends in the electronegativity of the substituent. The inductive effect is broadly classified as (i) negative inductive effect or -I effect. (ii) positive inductive effect or +I effect. Stability of given anions in the decreasing order is (i) bar(C)H_(3) " (ii) "bar(C)H_(2)-NO_(2)" (iii) "bar(C)H_(2)Cl" (iv) "CH_(3)-bar(C)H_(2)

Explain OH group attached to benzene ring activates it towards electrophilic substitution.
