Question 1
4 / -1

Benzenediazonium chloride on reaction with phenol in weakly basic medium gives

A
diphenyl ether

B
p-hydroxyazobenzene

C
chlorobenzene

D
benzene

Solution

Benzenediazonium chloride on reacting with phenol produces p-hydroxyazobenzene.
Question 2
4 / -1

An organic compound ‘A’ has the molecular formula C₃H₆O. It undergoes iodoform test. When saturated with HCl it gives ‘B’ of molecular formula C₉H₁₄O, ‘A’ & ‘B’ respectively are

A
propanal & mesitylene

B
propanone & mesityl oxide

C
propanone & 2, 6 – dimethyl – 2, 5 – heptadien – 4 – one

D
propane & meistylene oxide

Solution

Since the compound A has the molecular formula C₃H₆O & undergoes iodoform test, it should be CH₃COCH₃. Further reaction of B with HCl gives C₉H₁₄O, this should be trimer of acetone, i.e. It should be phorone.
