TEST-/11th, 12th & 12th Passed

Topic : Class XI 2nd Book

Date : 18 Feb 2015

Max Marks : 120 Time : 45 minutes

Section - I

Rapid Fire (+2/0)

This section contains 10 questions. In these questions for every ASSERTION a REASON is given, If Reason correctly explain Assertion then mark option ‘a’ in all other cases mark option ‘b’.

1. ASSERTION : CCl4 can not be hydrolysed

REASON : Carbon can not increase its coordination number greater than 4.

2. ASSERTION : E°Li+/Li is most negative among alkali metals

REASON : Li+(g) + H2O ® Li+(aq) DH of this reaction is highly negative

3. ASSERTION : BeCO3 is kept in atmosphere of CO2

REASON : In BeCO3 very weak lattices are found hence equilibrium of reaction

BeCO3 BeO + CO2 remain towards right even at room temp.

(s) (s) (g)

4. ASSERTION : Small amount of Glycerol is added in H2O2 bottles

REASON : Glycerol decrease the rate of decomposition of H2O2

5. ASSERTION : Boric acid is a two dimensional solid

REASON : Hydrogen bonding stabilize molecules of Trigonal H3BO3

6. ASSERTION : For nitration of benzene reactivity C6H6 = C6D6

REASON : Elimination of H+ is not a rate determining step

7. ASSERTION : B–F bond in BF3 is slightly shorter than expected

REASON : BF3 is a weaker Lewis acid

8. ASSERTION : Nitrogen in trisilyl amine is planar

REASON : lone pair of nitrogen does not participate in bonding

9. ASSERTION : In B2H6 all ‘H’ are not same

REASON : Two ‘H’ form electron deficient bonds

10. ASSERTION : Enthalpy of combustion of CH2 = CH2 >

REASON : Lesser the stability of alkene, higher the enthalpy of combustion.
