Alkylhalides have polar C-X bond and undergo nucleophilic substitution reactions. These give a variety of products with nucleophiles such as `-OH, -OR, -NH_(2), -CN, -NC, -NO_(2), -ONO, RCOO^(-)`, etc. They undergo mainly two types of nucleophilic substitution reactions, `S_(N)1` and `S_(N)2`. `S_(N)1` reactions are two steps reactions which proceed through the formation of carbocations while `S_(N)2` reactions are one step reaction which proceeds through the formation of transition state. The stability of carbocation and transition state determine the reactivity of alkyl halides.

Explanation

To complete the reaction of ethyl bromide (CH₃CH₂Br) with silver oxide (Ag₂O) under heat, we will follow these steps:

### Step 1: Identify the reactants
The reactants in this reaction are ethyl bromide (CH₃CH₂Br) and silver oxide (Ag₂O). Ethyl bromide is an alkyl halide, and silver oxide is a source of hydroxide ions (OH⁻) when it reacts.

### Step 2: Understand the reaction mechanism
When ethyl bromide is heated with silver oxide, the bromine atom (Br) is displaced. This is a nucleophilic substitution reaction, which can proceed via either the SN1 or SN2 mechanism. Given that Ag₂O can provide a nucleophile (OH⁻), we can expect a substitution reaction to occur.
