Answer the following:

Write the reaction to prepare acetaldehyde from hydrogen gas and an acid chloride.

A 10% aqueous solution of cane sugar (mol. wt 342) is isotonic with 1.754% aqueous solution of urea. Find the molecular mass of urea.

Determine the pH value of 0.001 M acetic acid solution if it is 2% ionised at this concentration. How can the degree of dissociation of this acetic acid solution be increased? 

Sulphur dioxide acts as an oxidizing agent as well as a reducing agent. Give one reaction to show its oxidizing nature and its reducing nature.

an organic compound A has the molecular formula C₇H₆O. When A is treated with NaoH followed by acid hydrolysis, it gives two products B and C. When B is oxidized it gives A, When A and C are each treated separately with PCl5, they give two different products D and E.

i) Identify A,B,C,D and E.
ii) Give the chemical reaction when A is treated with NaOH and name the reaction.
