Q2.101P - Chemistry: Molecular Nature Of Matter And Change

Question

Give the name and formula of the compound whose molecules consist of two chlorine atoms and one oxygen atom.

Step-by-Step Solution

Answer

Dichlorine monoxide is the chemical compound’s name, and its formula is $C{l}_{2}O$. 

Step 1: To give the Name and formula of a compound

The Objective is to name and calculate the formula for a compound with two Cl and one O atom.

The Number of atoms of an element is indicated by a subscript. So, the formula i$\mathit{C}{\mathit{l}}_{\mathbf{2}}\mathit{O}$ .

Step 2: To name the covalent compound

The element with the lower group number is indicated first when naming covalent compounds.However, compounds consisting of oxygen and halogen are an exception to that rule.The Halogen atom is listed first, followed by the oxygen atom with the suffix-ide.

The number of atoms of an element is indicated by a corresponding prefix(always added for the second element, even if mono).

Therefore,  name of$C{l}_{2}O$ isdichlorine monooxide.

Hence,dichlorine monoxide is the chemical compound’s name, and its formula is$C{l}_{2}O$.
