Which of the following reactions will not yield phenol? 

The reactivity order of halogenation of alkanes is $$F_2>Cl_2>Br_2>I_2$$ . Choose the correct statements.
(I) Lower the activation energy for the chain initiation step, more reactive is the halogen.
(II) Lower the activation energy for the first chain-propagation step, more reactive is the halogen.
(III) Lower the activation energy for the second chain-propagation step, more reactive is the halogen.
(IV) More negative is the overall heat of the reaction ( $$\Delta H_r^o$$ of the halogenation of alkane) more reactive is the halogen.
