There is a magnet on the side of the flywheel that passes the engine's magneto, which causes the spark plug to ignite the gas in the piston. The flywheel is held onto the crankshaft by the flywheel key.
Triphenylmethanol (also known as triphenylcarbinol, TrOH) is an organic compound. It is a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene.In strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable trityl carbocation.Many derivatives of triphenylmethanol are important dyes.n strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable trityl carbocation.

Ethyl methyl ether (three carbon atoms, one oxygen atom) is more soluble in water than 1-butanol (four carbon atoms, one oxygen atom), even though both can engage in hydrogen bonding with water.1  To give ethers common names, simply name the groups attached to the oxygen atom, followed by the generic name ether.ther molecules do have an oxygen atom, however, and engage in hydrogen bonding with water molecules. Consequently, an ether has about the same solubility in water as the alcohol that is isomeric with it.
