Aldehydes, Ketones and Carboxylic Acids

'x' is the product which is obtained from benzene by reacting it with carbon monoxide and hydrogen chloride in the presence of cuprous chloride. 'y' is the major product obtained from the benzene by reacting it with ethanoyl chloride in the presence of anhydrous AlCl3. Product (major) obtained by heating x and y in the presence of alkali is z. Total number of π (pi) electrons in z is .

'x' is the product which is obtained by the hydrolysis of prop-1-yne in the presence of mercuric sulphate under dilute acidic medium at 333 K. 'y' is the product which is obtained by the reaction of ethane nitrile with methyl magnesium bromide in dry ether followed by hydrolysis. IUPAC name of product obtained from 'x' and 'y' in the presence of barium hydroxide followed by heating is :

1. 2-Methylpent-4-en-3-one
2. 4-Methylpent-3-en-2-one
3. 4-Methylpent-1-ene
4. 2-Methylpent-3-one

" P " is a hydrocarbon of molecular formula:- C8H14. On ozonolysis, " P " forms "Q". "Q" on treatment with alkali under reflux condition produces "R", which on treatment with I2/NaOH gives a yellow precipitate. Acidification of the solution gives "S". The structure of "S" is given below:- [figure] The correct structure of P is
