Which unique property of carbon, by which it links with other carbon atoms to form long chains, allows it to form millions of compounds?

  1. Sublimation
  2. Ionisation
  3. Catenation
  4. Crystallisation
Show answer and solution

Correct answer: C. Catenation

1. The huge number of carbon compounds arises from carbon bonding to itself. 2. The property of an element joining with its own atoms to form chains is called catenation. 3. Carbon shows catenation strongly, so it forms long chains and rings. 4. Therefore the answer is catenation. _Source: Samacheer Kalvi (TN SCERT) Class 10 Science, Unit 11 "Carbon and its Compounds", p.162_

An open-chain hydrocarbon has all of its carbon atoms joined only by single bonds. The compound is classified as:

  1. Unsaturated
  2. Aromatic
  3. Saturated
  4. Heterocyclic
Show answer and solution

Correct answer: C. Saturated

1. The chain is open (acyclic), so it is not cyclic, aromatic or heterocyclic. 2. When every carbon-carbon bond in such a chain is a single bond, the compound is saturated. 3. Double or triple bonds would make it unsaturated, which is not the case here. 4. Hence the compound is saturated. _Source: Samacheer Kalvi (TN SCERT) Class 10 Science, Unit 11 "Carbon and its Compounds", p.163_

A cyclic organic compound has a closed ring made up of carbon atoms together with one oxygen atom. This compound is classified as:

  1. Alicyclic
  2. Carbocyclic
  3. Heterocyclic
  4. Aromatic
Show answer and solution

Correct answer: C. Heterocyclic

1. The ring is closed, so the compound is cyclic. 2. Rings made of only carbon are carbocyclic (homocyclic); this rules out carbocyclic, alicyclic and aromatic. 3. When the ring contains carbon and other atoms such as oxygen, nitrogen or sulphur, it is heterocyclic. 4. Since an oxygen atom is part of the ring, the compound is heterocyclic. _Source: Samacheer Kalvi (TN SCERT) Class 10 Science, Unit 11 "Carbon and its Compounds", p.163_
