Answer:
The boiling point will decrease to 73.3°C
Explanation:
Atmospheric pressure decreases with elevation and the boiling point of water is directly related to atmospheric pressure, it rapidly drops as elevation increases too, approximately 1°C for every 300 meters.
Answer: Option (D) is the correct answer.

General formula of an alkyne is .
Suffix "yne" in the name of a compound represents that there is a triple bond present in the compound.
So, a molecule of propyne will have three carbon atoms, four hydrogen atoms and a triple bond. Therefore, there wll be 6 sigma bonds and 2 pi bonds in a propyne molecule.
The last photo because its molecular formula is C3H4.
