(b)  CH₃\(-\)CH₂\(-\)Br \(\overset{aq. KOH}{\longrightarrow}\) ?

Answer 1

(I) Electrophiles: 

1. They are electron deficient. 

2. They are cations. 

3. They are lewis acids. 

4. Accept an electron pair. 

5. Attack on electron rich sites.

Nucleophiles:

1. They are electron rich. 

2. They are anions. 

3. They are lewis bases. 

4. Donate an electron pair. 

5. Attack on electron deficient sites.
