Which metal is most reactive according to the reactivity series? MCQ with Answer and Explanation

Which metal is most reactive according to the reactivity series?
A. Fe
B. K
C. Zn
D. Cu
Answer: Option B
Solution (By JKSSB Mock Tests)
Potassium (K) is at the top of the reactivity series, meaning it is the most reactive among the given metals. The order of reactivity (decreasing): K > Na > Ca > Mg > Al > Zn > Fe > Pb > Cu > Ag > Au. Potassium reacts violently with water and oxygen. Copper (Cu) is relatively unreactive and is found native in nature. Exam trick: Remember 'Please Stop Calling Me A Cute Zebra...' mnemonic.

Question #1
Which of the following compounds is electron-deficient?
A. H₂O
B. BF₃
C. CH₄
D. NH₃

Correct Answer: Option B


Explanation:
In BF₃, boron has 3 valence electrons and forms 3 covalent bonds with fluorine, resulting in only 6 electrons in its valence shell. It does not complete its octet, making it an electron-deficient molecule and a strong Lewis acid. NH₃, H₂O, and CH₄ all have complete octets.

Question #2
Sulphuric acid is called 'king of chemicals' because:
A. It is found in nature
B. It is used in the manufacture of many other chemicals
C. It is the cheapest acid
D. It is the strongest acid

Correct Answer: Option B


Explanation:
H₂SO₄ is used in production of fertilizers, detergents, dyes, explosives, petroleum refining, and many other chemicals. Its wide industrial use earns it the title. It's not the strongest (e.g., HClO₄ is stronger).

Question #3
Baking powder is a mixture of:
A. NaHCO₃ and NaCl
B. Na₂CO₃ and HCl
C. NaHCO₃ and acetic acid
D. NaHCO₃ and tartaric acid

Correct Answer: Option D


Explanation:
Baking powder = sodium bicarbonate + weak solid acid (usually tartaric acid or cream of tartar). On moistening, they react to produce CO₂, causing dough to rise without requiring external acidic ingredient.
