Chemical bonding — practice question

X, Y and Z are three elements that belong to Group 17. $\text{X}_2$ contains weaker covalent bonds than $\text{Y}_2$. The intermolecular instantaneous dipole-induced dipole forces in $\text{X}_2$ are stronger than those in $\text{Z}_2$. $\text{Y}_2$ acts as a stronger oxidising agent than $\text{Z}_2$. Which elements could X, Y and Z be?

  • AX = Br, Y = Cl, Z = I
  • BX = Cl, Y = Br, Z = I
  • CX = I, Y = Br, Z = Cl
  • DX = I, Y = Cl, Z = Br
