Question

Write the chemical formula for the covalent compound dichlorine heptoxide and mention its molecular weight in brackets after the formula.

Answer 1

Dichlorine heptoxide:

• Dichlorine heptoxide is a covalent compound which is basically an oxide of chlorine having molecular formula ${\mathbf{Cl}}_{\mathbf{2}}{\mathbf{O}}_{\mathbf{7}}$.
• It is the most stable chlorine oxide, a strong oxidizer as well as an explosive that can be set off with flame.
• It is composed of two chlorine atoms and seven oxygen atoms having a molecular weight equal to 182.906 g/mol [(2*35.453)+(7*16)].

Thus, the chemical formula and molecular weight of dichlorine heptoxide is ${\mathbf{Cl}}_{\mathbf{2}}{\mathbf{O}}_{\mathbf{7}}$ (182.906 g/mol ).
