(A) Clove bud powder (B) Clove bud powder with stalk
(C) Mother Clove (D) None of the above
Q.2 Arrange the following fatty acids in decreasing order of their unsaturation (highest to lowest):
[P] Stearic [Q] Oleic acid |R] Lmolenic acid |S] Linoleic acid
(A) P>Q>R>S (B) S>R>P>Q (C) R>S>Q>P (D) Q>P>R>S
Q.3 Determine the correctness or otherwise of the following Assertion [a] and the Reason [r]:
Assertion (a): Tannins are polyphenolic substances occurring in plant cell sap.
Hydrolysable and condensed tannins are differentiated by match stick test.
Reason (r) : The condensed tannins are resistant to acid hydrolysis therefore stain the lignin present in match stick.
(A) Both (a) and (r) are true, and (r) is a correct reason for (a)
(B) Both (a) and (r) are true, but (r) is NOT the correct reason for (a)
(C) (a) is true but (r) is NOT the correct reason for (a)
(D) Both (a) and (r) are false
ANS. B (AS U KNOW A &R TYPE QUE. ARE VERY IMP.PART OF OUR TEST SERIES . IN EVERY TEST U GET AROUND 3-5 QUE)
Q.4 Determine the correctness or otherwise of the following Assertion [a] and the Reason [r]:
Assertion (a): Castor oil is soluble in alcohol and is used as purgative.
Reason (r) : The oil contains ricinoleic acid having a hydroxyl group at C-12 position which is responsible for its solubility in alcohol and its purgative action.
(A) Both (a) and (r) are true but (r) is NOT the correct reason for (a)
(B) (a) is true but (r) is NOT the correct reason for (a)
(C) Both (a) and (r) are true and (r) is the correct reason for (a)
