Chemistry Class 12 Question Paper

SECTION : A
Read the given passage and answer the questions 1 to 5 that follow :
 
The halogens have the smallest atomic radii in their respective periods.
 
The atomic radius of fluorine is extremely small. All halogens exhibit – oxidation state. They are strong oxidising agents and have maximum negative electron gain enthalpy. Among halogens, fluorine shows anomalous behaviour in many properties. For example electro negativity and ionisation enthalpy are higher for fluorine than expected whereas bond dissociation enthalpy, m.p. and b.p. and electron gain enthalpy are quite lower than expected. Halogens react with hydrogen to give hydrogen halides (HX) and combine amongst themselves to form a number of compounds of the type XX', XX'3, XX'5 and XX'7 called inter-halogens.
 
1. Why halogens have maximum negative electron gain enthalpy ?
 
2. Why fluorine shows anomalous behaviour as compared to other halogens ?
 
3. Arrange the hydrogen halides (HF to HI) in the decreasing order of their reducing character.
 
4. Why fluorine is a stronger oxidizing agent than chlorine ?
 
5. What are the sizes of X and X' in the interhalogen compounds ?
 
Question 6 to 10 are one word answers.
 
6. Name the cell used in hearing aids and watches.
 
7. How much charge in terms of Faraday is required to reduce one mol of MnO4– to Mn2+ ?
 
8. Write the slope value obtained in the plot of log [Ro] / [R] Vs. time for a first order reaction.
 
9. Name the sweetening agent used in the cooking of sweets for a diabetic patient.
 
10. Name the polymer which is used for making electrical switches and combs.
 
Questions 11 to 15 are multiple choice questions.
 
11. In the Mond’s process the gas used for the refining of a metal is
(a) H2              (b) CO2
(c) CO              (d) N2
 
12. The conversion of an alkyl halide into an alcohol by aqueous NaOH is classified as
(a) a dehydrohalogenation reaction
(b) a substitution reaction
(c) an addition reaction
(d) a dehydration reaction
 
13. CH3CONH2 on reaction with NaOH and Br2 in alcoholic medium gives
(a) CH3CH2NH2            (b) CH3CH2Br
(c) CH3NH2                  (d) CH3COONa
 
14. The oxidation state of Ni in [Ni(CO)4] is
(a) 0              (b) 2
(c) 3              (d) 4
 
15. Amino acids are
(a) acidic               (b) basic
(c) amphoteric       (d) neutral
 
Questions 16 to 20.
 
(A) Both Assertion (A) and Reason (R) are correct statements, and Reason (R) is the correct explanation of the Assertion (A).
 
(B) Both Assertion (A) and Reason (R) are correct statements, but Reason (R) is not the correct explanation of the Assertion (A).
 
(C) Assertion (A) is correct, but Reason (R) is wrong statement.
 
(D) Assertion (A) is wrong, but Reason (R) is correct statement.
 
16. Assertion (A) : Conductivity of an electrolyte increases with decrease in concentration.
 
      Reason (R) : Number of ions per unit volume decreases on dilution.
 
17. Assertion (A) : The C-O-C bond angle in ethers is slightly less than tetrahedral angle.
 
      Reason (R) : Due to the repulsive interaction between the two alkyl groups in ethers.
 
18. Assertion (A) : Low spin tetrahedral complexes are rarely observed.
 
      Reason (R) : Crystal field splitting energy is less than pairing energy for tetrahedral complexes.
