Class 12 Chemistry Unit 7 Alcohols, Phenols and Ethers Worksheet with Answers
Question. The C — O bond is much shorter in phenol than in ethanol. Give reason.
Answer. Due to resonance C—O bond acquires some partial double bond character.
So, in phenol C—O bond length is smaller than ethanol.
Question. Which of the following isomers is more volatile :
o-nitrophenol or p-nitrophenol?
Answer. o-Nitrophenol is more steam volatile than p-Nitrophenol due to the presence of intramolecular H-bonding. p-nitrophenol shows intermolecular H–bonding.
Question. Give a chemical test to distinguish between 2-propanol and 2-methyl-2-propanol.
Answer. 2-propanol will give yellow precipitate of iodoform on addition of I2 and NaOH while 2-methyl-2-propanol will not.
Question. Write the equations involved in the following reaction :
Williamson synthesis
Answer. Williamson ether synthesis : Alkyl halide when treated with sodium alkoxide gives dialkyl ether.
C2H5ONa + C2H5Cl → C2H5 — O — C2H5 + NaCl
Question. Name the reagents which are used in the following conversions :
(i) A primary alcohol to an aldehyde
(ii) Butan-2-one to butan-2-ol
(iii) Phenol to 2, 4, 6-tribromophenol
Answer. (i) Copper at 573 K
(ii) Sodium borohydride (NaBH4)
(iii) Bromine water (Br2(aq))
Q1. What is absolute alcohol ?
Ans: 100% C2H5OH is known as absolute alcohol.
Q2. What is rectified spirit ?
Ans:95% C2H5OH is known as rectified spirit.
Q3.Lower alcohols are soluble in water but higher alcohols are not soluble . Why?
Ans: Due to large Hydrocarbon part which hydrophobic.
Q4. Why ether is insoluble in water ?
Ans: Due to absence of HB.
Q5. How is alcohol made unfit for drinking purposes ?
Ans: By adding CH3OH , CuSO4 and Pyridine
Q6. Phenol is an acid but does not react with NaHCO3. Why?
Ans: Since Phenol feebly weak in nature.
Q7.Diethylether does not react with Na.Why ?
Ans: Due to absence of acidic Hydrogen (Active).
Q8.Propanol has higher B.P. than that of n-Butane. Why?
Ans : In propanol there is HBonding but in n-Butane there is no HBonding.
Q9. Mixture of o- &p-Nitrophenol is separated by Steam volatile . Why ?
Ans: Due to intramolecular HB in O-Nitrophenol.
Q10. Out ofo- &p-Nitrophenol which one is more volatile ?
Ans:O-Nitrophenol due to intramolecular HB.
