Question

All lower hydrides of Group 14 elements share which common physical property and what is the reason for their boiling points?
Options
A They are colored solids with high boiling points due to strong intermolecular forces.
B They are colorless gases with low boiling points due to weak intermolecular attraction.
Correct Answer
C They are metallic liquids with moderate boiling points due to metallic bonding.
D They are viscous liquids with high boiling points due to hydrogen bonding.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 23 states, 'All lower hydrides are colourless gases.' and 'The liquids have low boiling points due to weak intermolecular attraction.'

Hint

Consider the nature of covalent hydrides and the typical forces between small, non-polar molecules.
