WebNaphthalene also undergoes addition reactions more readily than benzene. It is reduced by sodium and amyl alcohol to the tetrahydronaphthalene (XVIII) whereas benzene is unattacked by this reagent. The product (“tetralin”) is also obtained by partial catalytic hydrogenation of naphthalene. Webreaction + U fuse = 0 + w Electricity The sample and the fuse both undergo combustion. The electricity from the surroundings (work) heats the wire to a high temperature, and heats the system slightly before it and the sample explode in the nearly 40 atm of O 2 gas.
