The explosion limits of methane, ethane, propane, and butane decrease in sequence, with greater danger associated with each one? I hope there is an explanation from a fundamental perspective. Thank you.
This is because the wider the explosion limit, the greater the chances of explosion conditions occurring. The lower the lower explosion limit, the smaller amount of combustible material (such as a slight leak of flammable gas) will be sufficient to create explosive conditions ; The higher the explosion limit, the less air needs to penetrate into the container in order to mix with the flammable substances inside and create conditions for an explosion.

This is a chemical principle; those who study chemistry are just passing by here
Personal opinion: The explosive limit is expressed in terms of volume concentration. When this limit is reached, the greater the amount of substance in a given volume, the more energy is released during an explosion, and thus the greater the danger. Therefore, butane > propane > ethane > methane
The explosion limit is reduced, making it easier to reach that limit and thus increasing the risk
It can be understood from the reaction equation
