(A) Propanone

(B) Propanal

(C) Propanoic acid

(D) Propanol

Answer: (B) Propanal

Explanation: The compound contains an aldehyde group $(-CHO)$ and three carbon atoms. Therefore, its IUPAC name is Propanal.

The oxidation state of chromium in $ \text{K}_2\text{Cr}_2\text{O}_7 $ is:

(A) +3

(B) +4

(C) +6

(D) +7

Answer: (C) +6

Explanation: Let the oxidation state of Cr be $x$.

$2(+1) + 2x + 7(-2) = 0$

$2x = 12$

$x = +6$

Question 3

Which of the following is the strongest reducing agent?

(A) $ \text{Li} $

(B) $ \text{Na} $

(C) $ \text{K} $

(D) $ \text{Cs} $

Answer: (A) $ \text{Li} $

Explanation: Lithium has the most negative standard reduction potential and acts as the strongest reducing agent in aqueous solution.

Question 4

The hybridisation of carbon in ethyne $(\text{C}_2\text{H}_2)$ is:

(A) $sp$

(B) $sp^2$

(C) $sp^3$

(D) $dsp^2$

Answer: (A) $sp$

Explanation: Each carbon atom forms one triple bond and one single bond, resulting in $sp$ hybridisation.

Question 5

The value of pH of a $1 \times 10^{-3},\text{M}$ HCl solution is:

(A) 1

(B) 2

(C) 3

(D) 4

Answer: (C) 3

Explanation:

$\text{pH} = -\log [H^+]$

$= -\log(10^{-3}) = 3$
