Alcohols, Phenols and Ethers

Anisole is the product obtained from phenol by the reaction known as

• coupling

• etherification

• oxidation

• esterification

The epoxide ring consists of which of the following

• three membered ring with two carbon and one oxygen

• four membered ring with three carbon and one oxygen

• five membered ring with four carbon and one oxygen

• six membered ring with five carbon and one oxygen

In the Grignard reaction, which metal forms an organometallic bond?

• Sodium

• Titanium

• Magnesium

• Palladium

Phenol is more acidic than :

• p-chlorophenol

• p-nitrophenol

• o-nitrophenol

• ethanol

Trans esterification is the process of :

• conversion of an aliphatic acid to ester

• conversion of an aromatic acid to ester

• conversion of one ester to another ester

• conversion of an ester into its components namely acid and alcohol

Phenols are more acidic than alcohols because

• phenoxide ion is stabilised by resonance

• phenols are more soluble in polar solvents

• phenoxides ions do not exhibit resonance

• alcohols do not lose H atoms at all

  is the anhydride of 

• 1, 2-butane diol

• 2, 2-butane diol

• 2, 3-butane diol

• 1, 1-butane diol

1-chlorobutane on reaction with alcholic potash gives

• but-1-ene

• butan-1-ol

• but-2-ene

• butan-2-ol

Williamson's synthesis involves

• S_N1 mechanism

• nucleophilic addition

• S_N2 mechanism

• S_E mechanism

In the reaction

$2\mathrm{A} + \mathrm{dry}\hspace{0.17em}\mathrm{silver} \mathrm{oxide} \stackrel{∆}{\to } \mathrm{ether} + 2\mathrm{AgX} \mathrm{A} \mathrm{is} \mathrm{a}/\mathrm{an}$

• primary alcohol

• acid

• alkyl halide

• alcohol
