How acetophenone can be converted to phenol by reaction? a) m-CPBA followed by base catalysed hydrolysis
b) conc. HNO3
c) iodine and NaOH
d) Singlet oxygen followed by base catalysed hydrolysis product

m-CPBA followed by base catalysed hydrolysis

Explanation:

The scheme of this reaction is shown in the image attached.

We can see here that the acetophenone reacts with metachloroperoxybenzoic acid (m-CPBA) as shown in the image to yield phenyl acetate.

Phenyl acetate is now hydrolysed by a base as shown to yield the acetate ion and phenol.

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
