SECTION-A
 
Read the given passage and answer the questions 1 to 5 that follows:
 
Aromatic hydrocarbons are highly unsaturated. Aromaticity is ascertained by Huckel’s rule. Resonance stabilization in benzene makes it very stable that it doesn’t undergo addition reactions. They normally undergo electrophilic substitution reaction in the presence of Lewis acid catalysts. But in the absence of Lewis acid and in presence of light halogens add to benzene ring. The substituents present in benzene ring direct the incoming electrophile either into ortho and para or meta positions.
 
Q.1 What is Huckel’s rule?
 
Q.2 Is cyclohepta-1,3,5-triene aromatic? Why?
 
Q.3 Convert benzene to BHC.
 
Q.4 What is the directing nature of If NH2- group?
 
Q.5 Give the reaction for Friedel Craft’s alkylation of chlorobenzene
 
Questions 6 to 10 are one-word answers:
 
Q.6 Write Rydberg’s equation.
 
Q.7 Write the shape of AB2E3 type molecule.
 
Q.8 Write the state of hybridization of oxygen in H2O.
 
Q.9 Write the mathematical statement of first law of thermodynamics.
 
Q.10 Define disproportionation reaction with example.
 
Questions 11 to 15 are multiple choice questions:
 
Q.11 Identify correct statement regarding NH3 and BF3.
 
(a) Both are Lewis acid     (b) Both are iso structural
(c) Both are Lewis base    (d) Have different values of dipole moment
 
Q.12 Entropy of universe is :
 
(a) Increasing    (b) Decreasing    (c) Constant    (d) None of these
 
Q.13 Which one is ionic hydride in nature?
 
(a) CrH    (b) NH3    (c)H2O    (d) NaH
 
Q.14 Amphoteric hydroxides react with both alkalis and acids. Which of the following Group 2 metal hydroxides is soluble in sodium hydroxide?
 
(a) Be(OH)2    (b) Mg(OH)2    (c) Ba(OH)2    (d) Ca(OH)2
 
Q.15 Quartz is extensively used as a piezoelectric material, it contains ............
 
(i) Pb (ii) Si (iii) Ti (iv) Sn
 
Question16 to 20:
 
(A)Both assertion and reason are correct statements and reason is the correct explanation of the assertion.
 
(B) Both assertion and reason are correct statement, but reason is not the correct explanation.
 
(C) Assertion is correct but reason is wrong statement.
 
(D)Assertion is wrong but reason is correct statement.
 
Q.16 Assertion: Ionic radius of Na+ is smaller than Na.
Reason: Effective nuclear charge of Na+ is higher than Na.
 
Q.17 Assertion: Among the two O – H bonds in H2O molecule, the energy required to break the first O – H bond and the second O – H bond is the same.
Reason: This is because the electronic environment around the oxygen is the same even after breakage of one O – H bond.
 
Q.18 Assertion: Enthalpy of graphite is lower than that of diamond.
Reason: Entropy of graphite is greater than that of diamond.
 
Q.19 Assertion: Silicon is water repelling in nature.
Reason: Silicon is organosilicon polymers, which have (–R2SiO–) as repeating unit.
