Why is the major product of the reaction of 1-naphtol with benzene diazonium chloride not the ortho product?
When benzene diazonium chloride attacks the ortho position with respect to -OH it(the benzene ring) experiences a lot of steric hindrances,along with that,the triple bond also repels the lone pairs of oxygen,therefore the nitrogen atom will attack para with respect to the -OH group.If the temperature is increased i think that an ortho product will be formed as it is the thermodynamicly stable product,while the para product is the kinetically stable product.
