A
Addition of a hydrogen atom to an alkene
B
Elimination of a water molecule to form an ether
C

Verified step by step guidance1
Understand the concept of a nucleophilic substitution reaction: It involves the replacement of a leaving group in a molecule by a nucleophile.
Identify the role of the nucleophile: A nucleophile is an electron-rich species that donates an electron pair to form a new covalent bond.
Recognize the leaving group: In a nucleophilic substitution, the leaving group is the atom or group that is replaced by the nucleophile.
Analyze the reaction outcome: The key characteristic of a nucleophilic substitution is the formation of a new covalent bond between the nucleophile and the substrate, replacing the leaving group.
Differentiate from other reactions: Unlike addition or elimination reactions, nucleophilic substitution specifically involves the exchange of groups, not the addition of atoms or the removal of small molecules like water.
