Question

Titanium tetrachloride, $Ti{Cl}_4$, is a liquid at room temperature and has a very high vapor pressure. Which statement best explains these observations?

• A. Titanium tetrachloride is an ionic compound, with ${Ti}^{4+}$ and ${Cl}^{-}$ ions arranged in a lattice
• B. Titanium tetrachloride is a molecular substance, with $Ti{Cl}_4$ molecules held together by covalent bonds.
• C. The bonding in titanium tetrachloride is metallic, with a sea of electrons being shared equally between all the atoms in a sample.
• D. Titanium tetrachloride is a network covalent substance, with an essentially infinite lattice of covalently-bonded $Ti$ and $Cl$ atoms
• E. Titanium tetrachloride is simply a mixture of titanium atoms and chlorine atoms, which are not bonded to each other in any particular way.

Answer 1

The correct option is B Titanium tetrachloride is a molecular substance, with $Ti{Cl}_4$ molecules held together by covalent bonds.

Titanium tetrachloride consist of tetrahedral $TiC{l}_4$ molecules weakly held together by vander walls forces.$TiC{l}_4$ melts at at $-{23}^{0}C$.The wealk intermolecular forces constitute the points of structural weakness in such a crystal, and fusion at relatively low temperatures.
