NCl3= molecular compound

NaBr =  ionic compound

molecular  compound is formed  when two  non metals    form a bond by sharing electrons

in NCl3   electrons are  shared to each other

ionic compound is formed  when  a metal and a non-metal form a bond by losing and  gaining of electrons

In NaBr   Na is the metal  while Br is the non -metal. Na  loses  electrons while Br gain electrons
