When the planes hit the towers, the impact of the crash caused significant damage to the columns of the structures. They fire, very hot fire mind you, and fire balls created from the crash and explosion weakened much of the structure construction. All of the top portion that was weakened could no longer sustain itself and bore down on the rest of the structure thereafter. This caused the tower to collapse.
It took 102 Minutes for the North Tower to Collapse.
The plane was reaching 450 mph when it hit the south tower.

The plane hit the World Trade Center Building 7 in New York.
It collapsed an hour after it was hit with the first plane. remember 9/11
While there is a wide range of possible explanations for the collapse of the South Tower (2 WTC) before the North (1 WTC), it is believed that the lower impact of the plane on the tower (a full 15 stories under the same point on 1 WTC) and the passing of shrapnel and parts of the plane through three of four floor beams weakened the structure at an accelerated rate and brought 2 WTC down before its counterpart.
It took 102 Minutes for the North Tower to Collapse.
Yes, the North Tower (also referred to as 1 WTC) was the second of the towers to collapse.
