(C) If (A) is true but (R) is false. (D) If (A) is false but (R) is true.
Q.10 Assertion : Let z be a complex number satisfying
|z – 3| ≤ |z – 1|, |z – 3| ≤ |z – 5|, |z – i| ≤ |z + i|
and |z – i| ≤ |z – 5i|. Then the area of region in
which z lies is 12 sq. units.
Reason : Area of trapezium = 21 (sum of parallel
sides) (Distance between parallel sides)

Q. 10 Assertion (A) :As the earth revolves around the
sun it has an acceleration which is directed towards
centre of the sun.
Reason (R) :Angular momentum of the earth about
the sun remains constant.
Q. 11 Assertion (A) :In electric circuits , wires carrying
currents in opposite direction are often twisted
together.
Reason (R) : The magnetic field in the surrounding
space of a twisted wire system in not precisely zero.
Q.12 Assertion (A) : A metal ball is floating in mercury.
Coefficient of volume expansion of metal is less
than that of mercury. If temperature is increased,
fraction of volume immersed of metal will increase.
Reason (R) : Effect of heating on density of
mercury will be more compared to that of metal.

Section – II
This section contains 3 questions (Questions 1 to 3).
Each question contains statements given in two columns
which have to be matched. Statements (A, B, C, D) in
Column I have to be matched with statements (P, Q, R, S)
in Column II. The answers to these questions have to be
appropriately bubbled as illustrated in the following
example. If the correct matches are A-P, A-S, B-Q, B-R,
C-P, C-Q and D-S, then the correctly bubbled 4 × 4
matrix should be as follows :
P Q R S
S

P R R
Q Q
S S
R Q P
S RQ P A BC D
Mark your response in OMR sheet against the question
number of that question in section-II. + 6 marks will be
given for complete correct answer and No Negative
marks for wrong answer. However, 1 mark will be
given for a correctly marked answer in any row.

The following questions given below consist of an "Assertion" (A) and "Reason" (R) Type questions. Use the following Key to choose the appropriate answer.
(A) If both (A) and (R) are true, and (R) is the correct explanation of (A).
(B) If both (A) and (R) are true but (R) is not the correct explanation of (A).
(C) If (A) is true but (R) is false. (D) If (A) is false but (R) is true. Q. 10 Assertion (A) : N2F3
+ is planar at each nitrogen atom.
Reason (R) : In N3H, the bond angle H–N–N is 120° and both the N–N bond lengths are not equal.
Q. 11 Assertion (A) : A solution of [Ni(H2O)6]2+ is green but a solution of [Ni(CN)4]2– is colourless
Reason (R) : Energy difference between d levels (i.e. ∆) for H2O complex (paramagnetic) is in the visible region and that for the cyano complex (diamagnetic) is in the UV region
Q.12 Assertion (A) :Alkyl halides form cyanides with KCN but isocyanide with AgCN.
Reason (R) : KCN is an ionic compound and C–C bond is stronger than C–N bond. AgCN is a covalent compound and lone pair is present only on nitrogen.

cations are classified into various groups on the basis of their behaviour against some reagents. The group reagents used for the classification of most common cations are hydrochloric acid, hydrogen sulphide, ammonium hydroxide, and ammonium carbonate. Classification is based on whether a cation reacts with these reagents by the formation of precipitates or not.

Section – II This section contains 3 questions (Questions 1 to 3). Each question contains statements given in two columns which have to be matched. Statements (A, B, C, D) in Column I have to be matched with statements (P, Q, R, S) in Column II. The answers to these questions have to be appropriately bubbled as illustrated in the following example. If the correct matches are A-P, A-S, B-Q, B-R, C-P, C-Q and D-S, then the correctly bubbled 4 × 4 matrix should be as follows :
A B C D
