Sample questions

1. 1.Which reaction shows that phenols are stronger acids than alcohols?
   • A.Phenol reacts with aqueous NaOH to form sodium phenoxide, while alcohols do not
   • B.Both react with sodium metal to give hydrogen
   • C.Both form esters with carboxylic acids
   • D.Phenol dissolves in water
2. 2.Assertion (A): The boiling points of ethers are much lower than those of alcohols of comparable molecular mass. Reason (R): Unlike alcohols, ether molecules cannot associate with one another through intermolecular hydrogen bonding.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true
3. 3.Assertion (A): Phenol is a stronger acid than ethanol. Reason (R): The phenoxide ion is stabilised by delocalisation of the negative charge into the aromatic ring, whereas in the alkoxide ion the negative charge is localised on oxygen.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true
4. 4.Hydroboration-oxidation of a terminal alkene gives an alcohol in which the -OH group adds to the carbon that:
   • A.Carries the greater number of hydrogen atoms (anti-Markovnikov)
   • B.Carries the lesser number of hydrogen atoms (Markovnikov)
   • C.Is more substituted
   • D.Forms the more stable carbocation
5. 5.Williamson synthesis gives the best yield of ether when the alkyl halide used is:
   • A.Primary
   • B.Tertiary
   • C.Secondary
   • D.An aryl halide
