Verified step by step guidance

Step 1: Understand the concept of nucleophilic substitution reactions. These reactions involve the replacement of a leaving group by a nucleophile. A nucleophile is a species that donates an electron pair to form a chemical bond.

Step 2: Identify the key components of a nucleophilic substitution reaction. Typically, this involves an electrophile (often an alkyl halide), a nucleophile (such as a hydroxide ion), and a leaving group (such as a halide ion).

Step 3: Analyze the given options to determine which one fits the criteria for a nucleophilic substitution reaction. The reaction of an alkyl halide with a hydroxide ion to form an alcohol involves the hydroxide ion acting as a nucleophile, attacking the electrophilic carbon of the alkyl halide, and replacing the halide ion.

Step 4: Compare the other reactions listed. The addition of hydrogen to an alkene is a reduction reaction, the oxidation of a primary alcohol to an aldehyde is an oxidation reaction, and the dehydration of an alcohol to form an alkene is an elimination reaction. None of these involve nucleophilic substitution.

Step 5: Conclude that the reaction of an alkyl halide with a hydroxide ion to form an alcohol is the correct example of a nucleophilic substitution reaction, as it involves the key components and mechanism typical of such reactions.
