Hydrogenation of naphthalene (P) with excess hydrogen gas stops cleanly at 1, 2, 3, 4-tetrahydronaphalene (Q). What conclusion can be drawn from this experiment ? A. the hydrogenation of P is exothermicB. one aromatic ring of P is more reactive than the aromatic ring of QC. one aromatic ring of P is less reactive than the other ring of QD. reduction of the first `C = C` of P is faster than reduction of the second or third `C = C`
