Question

which of the following is correct about icl
a the name is iodine monochloride and not monoiodine monochloride because the \mono\ for the first cation - like element is dropped.
b the name should be chlorine iodide
c the name should be iodidechloride
d the name should be monoiodine monochloride since all atoms of all types must be shown in the name

Explanation:

In naming binary molecular compounds, the first - named element is the more electropositive one. For ICl, iodine (I) is more electropositive than chlorine (Cl). Also, the prefix "mono -" is not used for the first element when there is only one atom of it. So the name is iodine monochloride.

Answer:

A. The name is iodine monochloride and not monoiodine monochloride because the "mono" for the first cation - like element is dropped.
