False Statements:

(P) Oils with an oleic radical (1 double bond) are more suitable than oils with alinolenic radical (3 double bonds) as film forming vehicles for paints

(S) In the manufacture of urea from ammonia, the main intermediate product formed is ammonium bicarbonate

Explanation:

(P) This statement is false because oils with an alinolenic radical (3 double bonds) are more suitable for film-forming vehicles for paints because of their higher reactivity and ability to crosslink, which results in a harder and more durable film.

(Q) This statement is true because the production of synthesis gas from coal and steam requires energy input in the form of heat, making it an endothermic process.

(R) This statement is true because the use of chlorine in the bleaching of wood pulp can result in the formation of dioxins, which are toxic and persistent environmental pollutants.

(S) This statement is false because the main intermediate product formed in the manufacture of urea from ammonia is actually ammonium carbamate, not ammonium bicarbonate. Ammonium carbamate is subsequently dehydrated to form urea.

Overall, the false statements are (P) and (S).
