I am not totally sure but I think the answer shud be Compound-1.
Probable reasons-
1- First of all the H in compound 1 is more acidic than that of compound -2.
2- On forming the enol form of both compounds and comparing the stability of C=C, we see that no. of hyperconjugative structures, i.e, no of alpha H is more in Compound-1 than in Compound-2 thus stabilising its C=C more.
3- Cl, C=C, OH form a continuous chain of conjugation.

see 2nd one has large extended conjugation over the first one so more resonance structures no?

point of diff. is the presence of 1 Cl atom in the 1st molecule. Due to it, the H becomes more acidic and easily lost to form enol. hence greater enol content(extended resonance is present in both the molecule.
moreover, if the conversion is base catalized then rate of conversion is very much faster in 1st molecule>>>>>>>>>>>>>>>>>>>>>>>>>>>>
