Multiple Choice Questions

Question 1: Carborundum is
(a) calcium carbide
(b) silicon carbide
(c) beryllium carbide
(d) boron carbide
Show Answer & Explanation

Answer: (b) silicon carbide

Explanation:
1. Carborundum is silicon carbide, SiC, a very hard abrasive.

Teacher's Note:
1. Its hardness comes from a diamond-like structure.
2. It is used in grinding wheels.

Question 2: The main component of bio-gas is
(a) CO
(b) CO2
(c) H2
(d) CH4
Show Answer & Explanation

Answer: (d) CH4

Explanation:
1. Bio-gas from decomposing dung and plant waste is mostly methane (about 55 to 65 per cent) with some carbon dioxide.

Teacher's Note:
1. Methane is the fuel part.
2. The residue is a good manure.

Question 3: The chemist who made small artificial diamonds in 1893 by dissolving carbon in molten iron and cooling it suddenly was
(a) Moissan
(b) Moseley
(c) Mendeleev
(d) Markovnikov
Show Answer & Explanation

Answer: (a) Moissan

Explanation:
1. Henri Moissan heated sugar charcoal with iron in an electric furnace and cooled it quickly in water to get tiny diamonds.

Teacher's Note:
1. Moseley is linked with atomic number and Mendeleev with the periodic table.
2. Diamond is a crystalline form of carbon.

Question 4: Which of the following compounds is acidic?
(a) CH ≡ CH
(b) CH2 = CH2
(c) CH3 − CH3
(d) CH3 − Cl
Show Answer & Explanation

Answer: (a) CH ≡ CH

Explanation:
1. The hydrogen atoms of a triple-bonded carbon (as in ethyne) are weakly acidic and can be replaced by metals such as silver and copper. Ethene, ethane and chloromethane have no acidic hydrogen.

Teacher's Note:
1. The sp carbon holds its electrons tightly, so H leaves more easily.
2. Acetylides are formed from ethyne.

Question 5: An organic compound which is not heterocyclic is
(a) naphthalene
(b) thiophene
(c) pyrrole
(d) furan
Show Answer & Explanation

Answer: (a) naphthalene

Explanation:
1. Naphthalene has two fused rings made of carbon only. Thiophene, pyrrole and furan have S, N and O atoms in the ring, so they are heterocyclic.

Teacher's Note:
1. Hetero means different atom in the ring.
2. Naphthalene is aromatic and homocyclic.

Question 6: Which of the following is a thermoplastic?
(a) Bakelite
(b) PVC
(c) Melamine-formaldehyde resin
(d) Urea-formaldehyde resin
Show Answer & Explanation

Answer: (b) PVC

Explanation:
1. PVC softens on heating and can be remoulded, so it is a thermoplastic. Bakelite and urea-formaldehyde are thermosetting.

Teacher's Note:
1. Thermosetting plastics set permanently.
2. Polythene, PVC and polystyrene are thermoplastics.
