Concept Introduction : Atoms that have various numbers of neutrons and different masses but the same number of protons are called isotopes.
Answer to Problem 70A
The isotopes of the same element are chemically alike because they have the same number of electrons in them.
Explanation of Solution
The isotopes are the atoms of the same element that have the same number of protons and electrons but differ in the number of neutrons.
The isotopes are physically different because they have a different number of neutrons for an element.
Since the subatomic particles such as protons and electrons, which are responsible for chemical behavior, are present in equal proportions in isotopes, they are chemically similar.
Due to the same number of electrons, the isotopes are alike.

- The SN 1 mechanism starts with the rate-determining step which is the dissociation of the alkyl halide into a carbocation and a halide ion. The next step is the rapid reaction of the carbocation intermediate with the nucleophile; this step completes the nucleophilic substitution stage. The step that follows the nucleophilic substitution is a fast acid-base reaction. The nucleophile now acts as a base to remove the proton from the oxonium ion from the previous step, to give the observed product. Draw a curved arrow mechanism for the reaction, adding steps as necessary. Be sure to include all nonzero formal charges.
