Why was the helicopter invented by Igor Sikorsky?

Igor Sikorsky was one of many helicopter inventors. He was the one who invented a helicopter that used a tail rotor to counteract the thrust of the main rotor, and he was able to build one with a strong enough engine, an efficient enough rotor, and a light enough airframe. So his helicopter became the first successful commercially produced helicopter.

Why is a single rotor never used on helicopters?

In helicopter terms, the Rotor is actually the set of blades as a whole, individual blades are termed to be the rotor blades. So if you negate the Chinook, and a few other unusual types of helicopter, all helicopters utilise a single rotor. If you mean a single rotor blade, well again a single rotor blade design has been used on a helicopter.... An example of this was the Hiller HJ-1 Hornet, also the Boelkow 101/103 are good examples of this design.

What is a back rotor of a helicopter used for?

it depends. sometimes they make the helicopter turn. On models when they are facing up like the main rotor, they propell it forward so the gyro can fall to one side and lean the chopper forward. The major purpose of the back rotor is to counteract the torque of the main rotor. On helicopters with a single top rotor, if there were no back rotor, the torque would cause the helicopter to spin around as soon as it lifted off the ground.
