Which of the following is most reactive towards electrophilic substitution reaction?
1. | 2. | ||
3. | 4. |
In HS-, I-, RNH2, NH3 the correct order of proton accepting tendency will be:
1. | I- > NH3 > RNH2 > HS- | 2. | NH3 > RNH2 > HS- > I- |
3. | RNH2 > NH3 > HS- > I- | 4. | HS- > RNH2 > NH3 > I- |
The correct order of reactivity towards the electrophilic substitution of the compounds aniline (I), benzene (II), and nitrobenzene (III) is:
1. III > II > I
2. II > III > I
3. I < II > III
4. I > II > III
The compound that is least reactive towards nucleophilic substitution reaction is:
1.
2.
3.
