Answer 1

Also additionally to all the correct answers about engine clearance hight there were commercial airliners with rear mounted engines but due to the long momentum arm (both in the lateral and vertical plain) it was found to be undesirable in the case of an engine failure so that’s why the engines are mounted under the wings and forward.

Closer to the center of gravity so in the event of an engine failure the aircrafts have static stability and are controllable.

Smaller buissness jets have a smaller momentum arm and less powerful engines therfore are more staticly stable even in the event of a single engine failure.
