  1. A.Indian Navy and the Narcotics Control Bureau
  2. B.Indian Coast Guard and the Anti-Terrorism Squad, Gujarat
  3. C.Directorate of Revenue Intelligence and the Kerala Police
  4. D.Border Security Force and the Maharashtra Police

Correct answer: B. Indian Coast Guard and the Anti-Terrorism Squad, Gujarat

The Coast Guard put its ships and aircraft on the suspected boat, tracked it and boarded it on the high seas, while the state unit carried the case into arrest and investigation.

Q386.General ScienceEasy

Which functional group is present in ethanoic acid?

  1. A.Hydroxyl, -OH
  2. B.Aldehyde, -CHO
  3. C.Carboxyl, -COOH
  4. D.Ketone, -CO-
Show answer
Correct answer: C. Carboxyl, -COOH

Ethanoic acid, better known as acetic acid and familiar as vinegar in dilute form, has the formula CH3COOH, and the -COOH group at the end is what makes it acidic, since it releases a hydrogen ion in water and turns blue litmus red.

Q387.General ScienceMedium

The hardening of vegetable oil into vanaspati by passing hydrogen over a nickel catalyst is an example of

  1. A.Substitution reaction
  2. B.Addition reaction
  3. C.Displacement reaction
  4. D.Neutralisation reaction
Show answer
Correct answer: B. Addition reaction

Vegetable oils contain unsaturated chains with carbon to carbon double bonds; hydrogen adds across those double bonds in the presence of nickel or palladium, turning them into single bonds, so the oil becomes saturated and sets into a solid fat.

Q388.General ScienceMedium

Two consecutive members of a homologous series differ by

  1. A.CH2 and 14 units of mass
  2. B.CH3 and 15 units of mass
  3. C.C2H4 and 28 units of mass
  4. D.CH4 and 16 units of mass
Show answer
Correct answer: A. CH2 and 14 units of mass

Going from methane to ethane, or from ethanol to propanol, adds one carbon atom of mass twelve and two hydrogen atoms of mass one each, which is fourteen in all, and it is this fixed step that defines a homologous series.

Q389.General ScienceMedium

Why does graphite conduct electricity while diamond does not?

  1. A.Graphite contains metal impurities
  2. B.Each carbon atom in graphite has one free electron
  3. C.Graphite is made of a different element
  4. D.Diamond has a lower melting point
Show answer
Correct answer: B. Each carbon atom in graphite has one free electron

In graphite every carbon atom is bonded to only three others within a layer, so the fourth valence electron of each atom is free to move along the layer, and moving electrons constitute an electric current.

Q391.General ScienceAsked in: RRB NTPC · 13 Jun, 2025, Shift 1Easy

A gas stove flame burns blue because of

  1. A.Complete combustion of fuel
  2. B.Presence of hydrogen in the air
  3. C.Hazardous combustion
  4. D.Insufficient oxygen
Show answer
Correct answer: A. Complete combustion of fuel

When enough air reaches the burner, every carbon atom of the fuel is oxidised fully to carbon dioxide and the flame is blue and hot, giving the maximum heat for the gas consumed.

Q394.General ScienceAsked in: RRB Group D · 22 Oct 2018, Shift 2Medium

How many isomers does C6H14 have?

  1. A.3
  2. B.6
  3. C.4
  4. D.5
Show answer
Correct answer: D. 5

Hexane, C6H14, can be drawn as a straight chain of six carbons, as two chains of five carbons with a methyl branch in different positions, and as two chains of four carbons carrying branches, which gives five different structures with the same molecular formula.

Q395.General ScienceAsked in: RRB JE · 25 May 2019, Shift 3Easy

Cooking gas (LPG) mainly consists of

  1. A.Ethene
  2. B.Ethyne
  3. C.Propene
  4. D.Propane and Butane
Show answer
Correct answer: D. Propane and Butane

Liquefied petroleum gas is a mixture of these two saturated hydrocarbons, which are gases at ordinary pressure but turn liquid under moderate pressure, so a large quantity of fuel fits into a small cylinder; a strong-smelling compound is added so that a leak is noticed.

Q396.Indian PolityAsked in: SSC CGL · 21 Sep 2025, Shift 3Medium

  1. A.4 times

Show answer
Correct answer: C. Never

Article 360 has never been used. Even in 1991, when India faced a severe balance of payments crisis, had foreign exchange reserves for only a few weeks of imports and had to pledge gold to raise loans, the government chose economic reforms rather than a Financial Emergency.
