What is the common name of the lighter/fuel gas, formula C4H10?
Lighter the valve to release gas. The spark ignites the flammable gas causing a flame to come out of the lighter which continues until either the top is closed (naphtha type), or the valve is released (butane type). A metal enclosure with air holes generally surrounds the flame, and is designed to allow mixing of fuel and air while making the lighter less sensitive to wind. The high energy jet in butane lighters allows mixing to be accomplished by using Bernoulli's principle, so that the air hole(s) in this type tend to be much smaller and farther from the flame.

Gas lighter in a small region of air gap between two metallic points. Due to high voltage generated, the air is ionized and acts as a path for the discharge. This electric discharge is the spark which when exposed to the combustible gas from the stove ignites it to produce flame. In gas lighters, piezo-electric ceramics like lead zirconate titanate also known as PZT are used due to their low cost and high sensitivity. Before piezo-electric lighters became available, gas was often lit with a flint spark lighter. Some examples of these are shown below. Gas lighter A gas lighter is a
