RRB NTPC GK Questions 2026

Static General Knowledge makes up the rest of the General Awareness section in RRB NTPC, and the notices name its topics: General Science and Life Science up to Class 10, History of India and the freedom struggle, Physical, Social and Economic Geography of India and the world, Indian Polity and Governance, Indian Economy, Art and Culture, Indian Literature, Monuments and Places, Flora and Fauna, Famous Personalities, the UN and other world organisations, environmental issues, Transport Systems in India, Important Government and Public Sector Organisations, Common Abbreviations, and Basics of Computers and Computer Applications. RRB frames these as short factual questions: the unit of a physical quantity, the year of a battle, the article of the Constitution, the river a city stands on, the full form of an abbreviation, the headquarters of an organisation. GK24's GK notes on this page cover each topic in English and Hindi, arranged the way the syllabus lists them, with the facts RRB tends to ask placed first. Work through one topic at a time, note the lists (national parks, dances, articles, schedules, awards), and pair each topic with its quiz on GK24 to check what has stayed with you.

Q11861.General ScienceAsked in: RRB Group D · 4 Dec 2018, Shift 2Easy

What is the expected molecular mass of sulfur dioxide [SO2]?

  1. A.6.4 u
  2. B.65 u
  3. C.64 u
  4. D.6.5 u
Show answer
Correct answer: C. 64 u

Sulfur dioxide is made of one sulfur atom and two oxygen atoms, so its molecular mass is the sum of their atomic masses: 32 plus 2 multiplied by 16, that is 32 plus 32, which gives 64 u. Molecular mass is expressed in unified atomic mass units, written u, and…

Q11862.General ScienceAsked in: RRB Group D · 15 Oct 2018, Shift 2Medium

The formula unit mass of CaCl2 is:

  1. A.105 u
  2. B.111 u
  3. C.121 u
  4. D.100 u
Show answer
Correct answer: B. 111 u

Calcium chloride is an ionic compound, so it has a formula unit mass rather than a molecular mass, and the value is found by adding the atomic masses of all the atoms in the formula.

Q11863.General ScienceAsked in: RRB Group D · 17 Aug 2022, Shift 1Medium

Which of the following statements is INCORRECT? a) Methanoic acid is secreted by Nettle plant leaves. b) Acetic acid is found in vinegar. c) Tooth decay starts when mouth pH is lower than 5.5. d) Bacteria present in the mouth produce base by degradation of the remaining food particles present in the mouth.

Q11866.General ScienceAsked in: RRB Group D · 2 Sept 2022, Shift 1Easy

What is the formula of cyclohexane?

  1. A.C6H12
  2. B.C6H14
  3. C.C6H6
  4. D.C6H10
Show answer
Correct answer: A. C6H12

Cyclohexane is a closed ring of six carbon atoms joined by single bonds, and each carbon carries two hydrogen atoms, which gives C6H12.

Q11868.General ScienceAsked in: RRB Group D · 17 Dec, 2025, Shift 3Easy

Which of the following belongs to the alkyne group?

  1. A.C3H4
  2. B.C2H4
  3. C.C3H8
  4. D.C6H6
Show answer
Correct answer: A. C3H4

C3H4 is propyne, and it fits the alkyne general formula CnH2n-2 when n equals 3. Alkynes are unsaturated hydrocarbons that carry at least one carbon-to-carbon triple bond, and the first member of the family is ethyne, C2H2, better known as acetylene and burnt with oxygen in welding torches.

Q11870.General ScienceAsked in: RRB Group D · 10 Oct 2018, Shift 2Easy

Which of the following represents alkenes?

  1. A.—C = C—
  2. B.—C—C—
  3. C.H—O—H
  4. D.O = C = O
Show answer
Correct answer: A. —C = C—

An alkene is an unsaturated hydrocarbon in which two carbon atoms are joined by a double bond, so the carbon-to-carbon double bond is its identity.
