What is the main reason for the low boiling point of hydrogen compared to other group 1 hydrides?
Hydrogen forms stronger bonds
Hydrogen has a lower molecular weight
Hydrogen does not form hydrogen bonds
Hydrogen is a gas at room temperature
Hydrogen does not form hydrogen bonds like heavier group 1 hydrides, leading to a lower boiling point.

Q: What is the main reason for the low boiling point of hydrogen compared to other group 1 hydrides?
Solution: Hydrogen does not form hydrogen bonds like heavier group 1 hydrides, leading to a lower boiling point.
Steps: 5
Step 1: Understand what group 1 hydrides are. These are compounds formed between hydrogen and elements in group 1 of the periodic table, like lithium, sodium, and potassium.
Step 2: Recognize that heavier group 1 hydrides (like LiH, NaH, KH) can form hydrogen bonds due to their larger size and stronger interactions.
Step 3: Learn that hydrogen (H2) is a small molecule and does not have the ability to form hydrogen bonds like the heavier group 1 hydrides.
Step 4: Realize that hydrogen bonds are strong attractions between molecules, which increase the boiling point.
Step 5: Conclude that because hydrogen cannot form these strong hydrogen bonds, it has a lower boiling point compared to the heavier group 1 hydrides.
