(a)
Interpretation: The explanation corresponding to the given statement, “the homolysis of the
Concept introduction: The formation of carbocation, carbanion and free radical occur due to the heterolysis or homolysis process. Homolysis is opposite to the heterolysis. It forms radical with an unpaired electron.
Resonance is the delocalisation of
(b)
Interpretation: The reason for the shorter
Concept introduction: The bond length is inversely related to the bond strength. Bond length is defined as the distance between the centers of the nuclei of two bonded atoms in a molecule. It is determined by bond order. The increasing

- HBr addition to ethylene is exothermic. What does this mean? Options: The rate determining step is the first step. The newly formed bonds are more stable (higher dissociation energy) than those broken in the reactants. The carbocation intermediate is higher energy than the alkene. The reaction is very fast.arrow_forward11. Draw the structure for the molecule that would yield the products shown below under the indicated reaction conditions.
