Question

Which of the following statements correctly describes the tetrachlorides of Group 14 elements (e.g., CCl₄, SiCl₄)?
Options
A They are ionic solids with an octahedral shape.
B They are simple covalent molecules with a tetrahedral shape.
Correct Answer
C They are polar liquids with a trigonal planar shape.
D They are metallic solids with a linear shape.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document states, 'The tetrachlorides are simple covalent molecules with a tetrahedral shape and exist as liquids at room temperature and pressure.' It also notes they are 'non-polar' as a whole.

Hint

Consider the VSEPR theory for molecules with four electron domains around the central atom.
