9. H 2 C 2 O 4 and NaHC 2 O 4 behave as acids as well as<br />
reducing agents which is/are correct statement (s) ?<br />
(A) Equivalent wt. of H 2 C 2 O 4 and NaHC 2 O 4 are<br />
equal to their molecular weights when behaving<br />
as reducing agent<br />
(B) 100 mL of 1N solution of each is neutralised by<br />
equal volumes of 1M Ca(OH) 2<br />
(C) 100 mL of 1N solution of each is neutralised by<br />
equal volumes of 1N Ca(OH) 2<br />

This section contains 2 questions (Questions 10 to 11).<br />
Each question contains statements given in two<br />
columns which have to be matched. Statements (A, B,<br />
C, D) in Column I have to be matched with statements<br />
(P, Q, R, S, T) in Column II. The answers to these<br />
questions have to be appropriately bubbled as<br />
illustrated in the following example. If the correct<br />
matches are A-P, A-S, A-T, B-Q, B-R, C-P, C-Q and<br />
D-S, D-T then the correctly bubbled 4 × 5 matrix<br />
should be as follows :<br />

This section contains 8 questions (Questions 12 to 19).<br />
The answer to each of the questions is a SINGLE-<br />
DIGIT INTEGER, ranging from 0 to 9. The<br />
appropriate bubbles below the respective question<br />
numbers in the OMR have to be darkened. For<br />
example, if the correct answers to question numbers X,<br />
Y, Z and W (say) are 6, 0, 9 and 2, respectively, then<br />
the correct darkening of bubbles will look like the<br />
following :<br />
