- A. SO3
- B. SnCl2
- C. CO2
- D. BF3
Explanation: The correct answer is SnCl2. In SnCl2, the molecular geometry is bent due to the presence of a lone pair on the central atom, while the…
Correct answer: SnCl2- A. BF3
- B. H2O2
- C. PCl3
- D. PCl5
Explanation: The correct answer is BF3. In BF3, boron has only six electrons in its outer shell, resulting in an incomplete octet.

Correct answer: H2O, NH3, CH4- A. Trigonal
- B. Tetrahedral
- C. Octahedral
- D. Triangular
Explanation: The bond pair of electrons in the valence shell repel each other. To minimize the repulsions between the bond pairs, they are arranged at…
Correct answer: Tetrahedral- A. 1:2
- B. 1:4
- C. 1:6
- D. 3:6
Explanation: no of π Bonds (c-c)=3 no of σ Bonds (c-c)=6 no of σ bonds (c-h)=6 total σ bonds=6+6=12 ratio of π and σ=3/12 =1:4.
Correct answer: 1:4- A. sp, sp
- B. sp2, sp2
- C. sp2, sp
- D. sp3, sp2
Explanation: In the molecule CH2=C=CH2, the first and third carbon atoms (CH2 groups) are sp2 hybridized because they each form a double bond with the…
Correct answer: sp2, sp- A. C - O
- B. C = C
- C. C - C
- D. C = O
Explanation: The strongest bond among the given options is the C=O bond, with a bond energy of 799 kJ/mol.
Correct answer: C = O- A. 1st
- B. 2nd
- C. 3rd
- D. 4th
Explanation: As the graph shows three ionization energies increasing in order it must belong to an element of group 3 which possesses 3 valence…
Correct answer: 3rd- A. Be
- B. B
- C. N
- D. Ne
Explanation: N has half-filled valence p-orbital due to which it is more stable and thus its ionization energy is higher than oxygen even though…
Correct answer: N- A. I A
- B. II A, V A
- C. V A, VII A
- D. V A, VIII A
Explanation: The correct answer is Option B: II A, V A. Elements in group II A, such as alkaline earth metals, have filled s orbitals, which makes them…

- B. It forms positive ions
- C. It may form an ionic bond
- D. It belongs to the p-block
Explanation: The correct answer is D: It belongs to the p-block. Elements with low ionization energy are usually found in the s-block of the periodic…
Correct answer: It belongs to the p-block- A. C3H8
- B. C2H4
- C. C2H2
- D. SO2
