Realistic placements of Mountains and the like

This question basically boils down to this: What would be the places on a given continent where one would find mountains? I have seen maps from games, movies, board games, books etc. where it would seem mountains could almost be placed anywhere on a given landmass without any rhyme or reason. I also often hear mountains never occur alone without other mountains or hills near them.(as in, within 1km of one another so a mountain could never be surrounded by flat land) Any advice on this would be appreciated.

p.s. I heard volcanoes are an exception and those can occur anywhere (even surrounded by nothing but flat/low land) Is this true or also incorrect?
