Q3.Assertion (A): Carbon has a strong tendency to either lose or gain electrons to
attain noble gas configuration.
Reason (R): Carbon has four electrons in its outermost shell and has the tende
to share electrons with carbon or other elements.

assertion (A).
3. (A) is true, but (R) is false.
4. (A) is false, but (R) is true.
Q4.For question two statements are given- one labelled Assertion (A) and the othe
labelled Reason (R). Select the correct answer to these questions from the cod
(a), (b), (c) and (d) as given below:
1. Both A and R are true, and R is correct explanation of the assertion.

Q7.A student adds a few drops of ethanoic acid to test tubes X, Y and Z containing
aqueous solutions of sodium chloride, sodium hydroxide and sodium carbonat
respectively. If he now brings a burning splinter near the mouth of the test tube
immediately after adding the ethanoic acid in each one of them, in which of th
test tube or test tubes the flame gets extinguished?
1. X and Y
2. Y and Z
3. X and Z
4. Only Z
Q8.A student takes about 6 ml of distilled water in each of the four test tubes P, Q,
and S, then dissolves an equal amount of four different salts namely sodium
chloride in ‘P', potassium chloride in ‘Q', calcium chloride in ‘R' Cand magnes
chloride in ‘S'. He then adds 10 drops of soap solution to each test tube and sh
its contents. The test tubes in which scum (insoluble substance) is formed with
soap are:
1. P and Q
2. Q and R
3. R and S
4. Q and S
Q9.A reaction scheme is shown below:
