Q1. Using standard electrode potentials, the strongest oxidizing agent among Cl₂, Br₂ and I₂ is:

  1. Br₂
  2. Cl₂
  3. I⁻
  4. I₂
Show the answer

Answer: B. Cl₂

More positive E° ⇒ stronger oxidizing agent; more negative E° ⇒ stronger reducing agent.

Q2. Which of these is a weak base?

  1. calcium hydroxide (dissolved)
  2. sodium hydroxide
  3. barium hydroxide
  4. methylamine
Show the answer

Answer: D. methylamine

The correct answer is “methylamine”. Methylamine: weak base.

Q3. The outer electron configuration of strontium (Sr, Z = 38) is:

  1. [Kr] 5s²
  2. [Ne] 3s²
  3. [He] 2s²
  4. [Kr] 5s¹
Show the answer

Answer: A. [Kr] 5s²

The correct answer is “[Kr] 5s²”. Group 2: ns².

Q4. The coordination number of the metal in [Co(NH₃)₆]³⁺ is:

  1. 6
  2. 4
  3. 2
  4. 3
Show the answer

Answer: A. 6

The correct answer is “6”. Number of dative bonds to the metal: 6.

Q5. Which term means compounds with the same structural formula but different spatial arrangements of atoms?

  1. racemic mixture
  2. chiral centre
  3. stereoisomers
  4. enantiomers
Show the answer

Answer: C. stereoisomers

Stereoisomers: compounds with the same structural formula but different spatial arrangements of atoms.

Q6. The reaction of phenol + concentrated HNO₃ gives:

  1. no effervescence (phenol is too weak an acid)
  2. 2,4,6-trinitrophenol (picric acid)
  3. a white precipitate of 2,4,6-tribromophenol
  4. sodium phenoxide and hydrogen gas
Show the answer

Answer: B. 2,4,6-trinitrophenol (picric acid)

Phenol + concentrated HNO₃: 2,4,6-trinitrophenol (picric acid).
