When phenol is heated strongly with zinc dust the product formed is

Action of heat on mixture of anhydrous sodium propionate and soda lime produces

When a white crystalline compound 'X' is heated with K_(2)Cr_(2)O_(7) and concentrated H_(2)SO_(4) a red dish brown gas 'A' is evolved. On passing 'A' into caustic soda solution, a yellow coloured solution of 'B' is obtained. Neutralising the solution 'B' with acetic acid and on subsequent addition of lead acetate a yellow precipitate C is obtained. When 'X' is heated with NaOH a colourless gas is evolved and on passing this a gas into K_(2)HgI_(4) (Nessler's reagent) solution a reddish brown precipitate D is formed. Identify '(A), (B), (C), (D) and X. Write equations for the reactions involved.

An organic compound A on treatment with CHCl_3 and KOH gives two compounds B and C . Both B an C give the same product (D) when distilled with zinc dust. Oxidation of D gives E . having molecular formula C_7 H_6 O_2 . The sodium salt of E on heating with soda lime gives F which may also be obtained by distilling A with zinc dust. Identify A to F ,

CH_(3)COOC_(2)H_(5) on reaction with sodium ethoxide gives a compound ‘X’ which on hydrolysis in presence of acid gives another compound ‘Y’ which on heating gives ‘Z’. Which of the following are X, Y, and Z respectively?
