Which of the following best explains the difference in behavior between PH3 and NH3 when introduced slowly into water?
Options
- APH 3 and NH 3 have similar molecular structures, so they both dissolve in water.
- BPH 3 and NH3 both form hydrogen bonds with water, causing them to dissolve.
- CNH 3 forms hydrogen bonds with water, making it soluble, while PH 3 cannot form hydrogen bonds and escapes as
- DPH 3 forms hydrogen bonds with water, making it soluble, while NH 3 cannot form hydrogen bonds and escapes as
Correct answer
C. NH 3 forms hydrogen bonds with water, making it soluble, while PH 3 cannot form hydrogen bonds and escapes as
Step-by-step solution
Correct Option is : (C) NH 3 forms hydrogen bonds with water, making it soluble, while PH 3 cannot form hydrogen bonds and escapes as a gas.
