Free Chemical Bonding MCQs with Answers

964 Chemical Bonding MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.

Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.

Explanation: High-profile protests and resignations by ministers (Statement II) create significant political pressure.

Correct answer: Statement II is the cause and statement I is its effect
  • A. Only I follows
  • B. Only II follows
  • C. Either I or II follows
  • D. Neither I nor II follows

Explanation: The low female‑to‑male ratio needs verification before any action. Conducting another census (I) is sensible to confirm the data, while…

Correct answer: Only I follows
  • A. sp3
  • B. dsp2
  • C. d2 sp3
  • D. dsp3

Explanation: d2sp3 is correct because it corresponds to the hybridization of Pt in the square planar complex [Pt(NH3)4]2+.

Correct answer: d2 sp3
  • A. sp?
  • B. sP*
  • C. SP
  • D. dsp

Explanation: hybridization in BeCl2 is sp hybridization because as only s and one p subsub shell hybridize to form two lobes which make linear…

Correct answer: SP
  • A. Trigonal planar, 120°, sp2
  • B. Trigonal planar, 120°, sp3
  • C. Trigonal planar, 109.5°, sp2
  • D. Trigonal pyramidal, 120°, sp2

Explanation: The correct answer is Option A: Trigonal planar, 120°, sp2. A carbocation like CH3+ has sp2 hybridization because the carbon atom is…

Correct answer: Trigonal planar, 120°, sp2
  • A. CH3CH2CH3
  • B. CH3C≡CH
  • C. CH3CH=CH2
  • D. CH2=CH-CH=CH

Explanation: In option A all Carbon are linked together by sp3 hybrization hence that option is correct.

Correct answer: CH3CH2CH3
  • A. 60°
  • B. 120°
  • C. 90°
  • D. 180°

Explanation: As ethene has sp2 hybridization hence the bond angle between H and C atom connected to same C will be 120

Correct answer: 120°
  • A. sp3
  • B. sp2
  • C. sp
  • D. dsp2

Explanation: The number of monovalent atoms attached to C is two. This suggests that C in ethylene (H₂C=CH₂) is sp² hybridised.

Correct answer: sp2
  • A. Option A: BF3
  • B. Option B: C2H4
  • C. Option C: BeCl2
  • D. Option D: CH4

Explanation: The correct answer is Option D: CH4. Methane exhibits sp3 hybridization as the carbon atom forms four sigma bonds, leading to a…

Correct answer: Option D: CH4
  • A. One 1s, one 2p
  • B. One 2s, three 2p
  • C. One 2s, two 2p
  • D. One 2s, one 2p

Explanation: sp hybridization is the mixing of one s orbital and one p orbital from the same valence shell of an atom.

Correct answer: One 2s, one 2p
  • A. 25%
  • B. 33.3%
  • C. 50%
  • D. 75%

Explanation: In sp2 hybrid orbital% of s character =1/3 x 100=33.3%In sp3% of p character = 3/4 x 100 = 75%

Correct answer: 33.3%
  • A. 25%
  • B. 75%
  • C. 50%
  • D. 33%

Explanation: An sp³ hybrid orbital is formed from one s orbital and three p orbitals, making a total of four orbitals.

Correct answer: 75%
  • A. 120°
  • B. 180°
  • C. 109.5°
  • D. 90°

Explanation: One s orbital and two p orbitals of the central atom combine These hybrid orbitals are arranged in a trigonal planar geometry, with an…

Correct answer: 120°
