As the NO 2 + ion approaches the delocalised electrons in the benzene, those electrons are strongly attracted towards the positive charge.. Two electrons from the delocalised system are used to form a new bond with the NO 2 + ion. x��X�o�FG����>�e���"�@�*��)U����BH�J0u��r}g�6���B�ò�����o>vt����epy�׃�� �n�8p�9R�"��h������-KnW�Ft�����݂�/�� Q�Y�d�AB�nu/ �{��@�b��O�����v�&�&��6��v��V~���v�|��_�qLI�,�s(!�l����d)�9�f4%���9ڎ�?����P�
