Liquid Properties
1. A liquid crystalline state exists between two temperatures (the melting temperature and the ______ temperature).
- A. Boiling
- B. Freezing
- C. Clearing
- D. All of these options are correct
View answer and explanation
Answer: C. Clearing
A liquid crystal exists in the mesophase between the melting temperature (solid to liquid crystal) and the clearing temperature (liquid crystal to clear isotropic liquid). Boiling and freezing do not bound this phase. Hence the second boundary is the clearing temperature.
Hydrogen Bonding
2. Which pair can form hydrogen bonds with each other?
- A. H2 and He
- B. CO2 and
- C. H2O and NH3
- D. CH4 and CCl4
View answer and explanation
Answer: C. H2O and NH3
Water and ammonia each have donor hydrogens and lone-pair acceptors.
Hydrogen Bonding
3. Which of the following substances exhibits hydrogen bonding? (MDCAT 2017)
- A. HI
- B.
- C.
- D.
View answer and explanation
Answer: C.
Hydrogen bonding needs H attached to N, O or F. N and C OH qualify; HI, S, Si , CHC do not. Hence N is correct. A ('HI'), B (' S') and D ('Si ') lack an H–N/O/F bond.
