Answer:-
Methane itself is completely odorless and colorless. However, the natural gas used in homes, which contains methane, has a strong rotten egg smell. This odor comes from an added chemical called mercaptan, which helps detect gas leaks for safety. Since pure methane has no scent, it can be dangerous if it leaks in an enclosed space without being noticed. High concentrations can lead to explosions or suffocation. That’s why gas companies add mercaptan—it acts as a warning sign. If you ever smell gas in your home, it’s important to leave the area and report the leak immediately.
