Select the correct statements:
(1) Destruction of ozone is made by chlorine radical by providing a path with much lower activation energy.
(2) The function of tetraethyl lead to increase octane number is due to its dissociation on heating and thereby providing ethyl free radical.
(3) The enzyme carbonic anhydrase catalyses the reaction of $C O_{2} (g)$ and $H_{2} O (l)$ in human body to produce $H^{+} (a q)$ and $H C O_{3}^{-} (a q)$ .
(4) Anhydrous $C u S O_{4}$ absorbs $H_{2} O$ .

Q. In the free radical chlorination, the two factors which determine the product ratio of various monochlorination products are the type of H being substituted and the number of a specific type of H being substituted. If activation energy for H-abstraction by chlorine radical is considered to be zero, what would be the percentage of l-chlorobutane amongthe monochlorobutanes obtained on free radical chlorination of butane?
