Exercise 4

At higher temperature, iodoform reaction is given by dilute solution of:

Which of the following product is formed when benzaldehyde is treated with ${\mathrm{CH}}_3\mathrm{MgBr}$ and the addition product so obtained, is subjected to acid hydrolysis?

An ether is more volatile than an alcohol having the same molecular formula. This is due to:

$\mathrm{P}-$cresol reacts with chloroform in alkaline medium to give the compound $\mathrm{A}$ which adds hydrogen cyanide to form, the compound $\mathrm{B}$. The latter on acidic hydrolysis gives chiral carboxylic acid. The structure of the carboxylic acid is
