1. Activation :-a, b, k, m, n, o, s, t. Deactivation :-c, d, e, f, g, h, i, j, l, p, q, r. Steric Hindrance: The ortho position is closer to the existing substituent, leading to steric repulsion between bulky groups. The para position is farther away, minimizing this steric interference. 2.A-a, e, c B-a, c, e C-c, e 3.A-a, c B-a C-a, c 4.A-a, b, d B-a, b, d, f C-b, d Sigma Bond Formation: When the electrophile attacks the aromatic ring, it forms a new bond with one of the carbon atoms of the ring. This bond is a sigma bond, which is a single covalent bond formed by the overlap of atomic orbitals. This new sigma bond disrupts the aromaticity of the ring temporarily. 2. Intermediate Structure: The intermediate species, known as the sigma complex or arenium ion, has a positively charged center on the ring due to the electron donation from the ring being partially disrupted. The delocalization of the charge in the intermediate occurs through the sigma bonds, hence the name "sigma complex." 5.A-b, d B-b, d C-a, b 6.A-a, c B-b C-b, d 7.A-a, c B-c C-a, c 8.A-b, d B-b, d C-b, c
