How does propene react with:
(i) Hydrogen  
(ii) Bromine
(iii) Water in the presence of mineral acid
(iv) Chlorine water (or hypochlorus acid)?

---

(i) Action with hydrogen: Propene reacts with hydrogen in the presence of nickel, platinum or palladium as a catalyst at 523-573 K to form propane.



(ii) Action with bromine: Propene reacts with bromine (in CCl₄) to form 1, 2-Dibromopropane.



(iii) Action with water: Propane reacts with water in the presence of mineral acid to form propan-2-ol.



(iv) Action with chlorine water: Propene reacts with chlorine in the presence of water to form propylene chlorohydrin.
