On the basis if above passage, answer the questions

When tow different halogens react with each other, interhalogen compounds are formed. They can be assigned general compositions as \(XX'\), \(XX'_3\), \(XX'_5\); and \(XX'_7\), where \(X'\) is a halogen of larger size and \(X\) of smaller size and X is more electropositive than X increases, the number of atoms per molecule also increases.

\(ClF_3\) is ______ and ________ structure

Colourless gas, Bent T-shaped

The correct answer is option 2. Colourless gas, Bent T-shaped.

Chlorine trifluoride (\(ClF_3\)) is a colorless gas at room temperature and atmospheric pressure. This means that in its pure form, it does not exhibit any noticeable color. However, it's essential to note that impurities or decomposition products may sometimes give it a yellowish or brownish appearance.

The molecular geometry of \(ClF_3\) is described as Bent T-shaped. In this molecular arrangement, the central chlorine atom is surrounded by three fluorine atoms and has two lone pairs of electrons. The presence of these lone pairs affects the arrangement of the fluorine atoms, resulting in a Bent T-shaped molecular geometry. This geometry is due to the repulsion between electron pairs around the central atom.

So, when considering the properties of \(ClF_3\), it's a colorless gas due to its molecular composition and arrangement, and its Bent T-shaped molecular geometry contributes to its reactivity and chemical behavior.
