    "long bond" means the lehgth of covalent bond is long enough.

    It is formed by two large atoms like iodin and bromine, etc.

    Reaction mechanism means the path of reaction going.

    for example:

    a reaction 2A+B+C---->D

    the mechanism maybe:

    A+B--->S

    S+C---->r

    r+A---->D

    Sometimes, one reaction possesses several mechanisms dependent on the reaction conditions such as temperature, pressure, catalyst and the dose. However, it is impossible for people who can write down equation or mechanism of a reaction without any experiments.
