NEET Chemistry (general) MCQ Question
Which combination of statements correctly describes the properties and behavior of ammonia and its derivatives?
Ammonia is a colorless gas with a pungent odor; it forms ammonium salts with acids; its aqueous solution is a strong base.
Ammonia has a trigonal pyramidal shape; it is highly soluble in water; it significantly raises the pH of water.
Ammonia is associated through hydrogen bonds in solid state; it has higher boiling points than expected; it has three bond pairs and one lone pair.
Ammonia can precipitate hydroxides; it is a liquid at room temperature; it has no effect on pH.
Correct Answer
Detailed Explanation
Ammonia is indeed associated through hydrogen bonds in its solid state, leading to higher boiling points than expected based on molecular mass, and it has a trigonal pyramidal shape with three bond pairs and one lone pair of electrons.
