The tetrahalides of group 14 elements except that of carbon are:
The tetrahalides of group 14 elements except that of carbon are:
Open in App
Solution
The correct option is C strong Lewis acids
The tetrahalides are covalent and have tetrahedral geometry. Their thermal stability decreases down the group and the tetrahalides of group 14 except that of carbon are readily hydrolysed. In carbon there is no vacant d-orbitals so it cannot increase its valency beyond four. The halides of carbon do not act as lewis acids.
