1 4 addition 1 4 addition is an electrophilic addition reaction of conjugate dienes.
Look at the atoms directly bonded to the yellow circled carbons and list them in decreasing atomic number.
Carbon a has three hydrogens attached to it and carbon b has one carbon and two hydrogens since carbon has a higher atomic number than hydrogen branch b has the higher priority.
