this is 1,3 pentadiene which is conjugated diene shows resonance .if we add bromine at low temperature at 0 degree it form 1,2 -position addition while at high temperature at 40 -80 degree range it form 1,4 addition product as major.this is explain by competition between chemical kinetics and thermodynamical control reaction.normally at low temperature kinetically control product is major while at high temprature thermodynimacally product is major.
