The property of carbon to form bonds with itself is called: MCQ with Answer and Explanation

The property of carbon to form bonds with itself is called:
A. Catenation
B. Tetravalency
C. Isomerism
D. Polymerisation
Answer: Option A
Solution (By JKExamLibrary)
Catenation is the ability of carbon atoms to form long chains, rings, and networks via covalent bonds. This leads to a vast number of organic compounds. Silicon also catenates but to lesser extent.

Question #1
The indicator phenolphthalein turns pink in:
A. Neutral medium
B. Basic medium
C. Acidic medium
D. All media

Correct Answer: Option B


Explanation:
Phenolphthalein is colorless in acidic and neutral solutions, turning pink/magenta in basic solutions with pH > about 8.2-10. It is commonly used in acid-base titrations. Methyl orange is red in acidic and yellow in basic. Litmus is purple in neutral, red in acid, blue in base. Natural indicators like turmeric, beetroot also show color changes.

Question #2
DAP (diammonium phosphate) provides which primary nutrients to plants?
A. P and K
B. N and P
C. N and K
D. N, P, and K

Correct Answer: Option B


Explanation:
DAP, (NH₄)₂HPO₄, supplies nitrogen (18% N) and phosphorus (46% P₂O₅). It is a widely used phosphorus-rich fertilizer. Potassium is not present. NPK complex fertilizers provide all three. DAP is highly water-soluble, making phosphorus readily available. In soil, DAP temporarily increases pH around granules due to ammonia, but later nitrification lowers pH. Application: usually at sowing time.

Radioactive isotope used in dating ancient objects is:
A. Iodine-131
B. Carbon-14
C. Uranium-235
D. Cobalt-60

Correct Answer: Option B


Explanation:
Carbon-14 dating is used to determine age of organic materials up to ~50,000 years based on its half-life of 5730 years. Cobalt-60 for cancer therapy, iodine-131 for thyroid, uranium-235 for nuclear fuel.
