Chapter 2.2, Problem 2.8E

(a)

Interpretation Introduction

Interpretation: The category of reaction from below substrates should be identified along with the product formed in the reaction and appropriate curved arrows should be used to show electron movement.

  $\begin{array}{l}\left(i\right){\text{CH}}_3{\text{O}}^{-}+{\text{H}}^{+}\\ \left(ii\right){\text{H}}^{+}+{\text{CH}}_3{\text{CH=CHCH}}_3\\ \left(iii\right){\left({\text{CH}}_3\right)}_2{\text{N}}^{-}+\text{HCl}\\ \left(iv\right){\text{CH}}_3{\text{O}}^{-}+{\text{O=CH}}_2\end{array}$

Concept introduction: The fundamental electrostatics suggests that electrons have more affinity for electron-deficient sites in an organic compound or positive charge. The curved arrow is appropriate mechanism to depict electron movement that occurs from electron rich species to electron-deficient species.

(b)

Interpretation Introduction

Interpretation: The wrong thing about below arrow diagrams should be indicated.
