Which of the following statements is incorrect regarding the properties of elements of Group 15?
- Bismuth shows metallic properties
- Nitrogen exists as diatomic molecule
- All elements exhibit allotropy
- The stability of hydrides decreases down the group
Show answer & explanation
Answer: C. All elements exhibit allotropy
Not all elements of group 15 exhibit allotropy. For example, Nitrogen does not show significant allotropy under normal conditions.

Which of the following compounds has the highest lattice energy?
- NaCl
- KCl
- MgCl₂
- CaCl₂
Show answer & explanation
Answer: C. MgCl₂
Lattice energy is directly proportional to the charge of the ions and inversely proportional to the size of the ions. Mg²⁺ and Cl⁻ have higher charges compared to Na⁺ and K⁺ while the sizes are comparable, so MgCl₂ has the highest lattice energy.

What is the IUPAC name of the compound CH₃CH(Cl)CH₂CH=CH₂?
- 2-Chloro-4-pentene
- 4-Chloro-1-pentene
- 2-Chloro-1-pentene
- 4-Chloro-4-pentene
Show answer & explanation
Answer: A. 2-Chloro-4-pentene
The longest carbon chain containing the double bond has five carbons. The double bond is at position 1, and the chlorine is at position 2. Hence, 2-Chloro-4-pentene.

The pH of a solution obtained by mixing 50 mL of 0.2 M HCl and 50 mL of 0.1 M NaOH is:
- 7
- 2
- 1
- 1.3
Show answer & explanation
Answer: C. 1
Moles of HCl = 50 mL * 0.2 M = 10 mmol; Moles of NaOH = 50 mL * 0.1 M = 5 mmol. After neutralization, moles of HCl remaining = 10 - 5 = 5 mmol. Total volume = 100 mL. [H⁺] = 5 mmol / 100 mL = 0.05 M. pH = -log(0.05) ≈ 1.3. This is closest to 1.

Which of the following is the strongest oxidizing agent?
- F₂
- Cl₂
- Br₂
- I₂
Show answer & explanation
Answer: A. F₂
Fluorine (F₂) is the strongest oxidizing agent among the halogens due to its high electronegativity and small size.

What is the role of cryolite in the metallurgy of aluminium?
- To lower the melting point of Al₂O₃
- To increase the electrical conductivity
- To reduce Al₂O₃
- Both A and B
Show answer & explanation
Answer: D. Both A and B
Cryolite (Na₃AlF₆) lowers the melting point of alumina (Al₂O₃) and increases the electrical conductivity of the molten mixture, facilitating the electrolytic reduction of aluminium.

Which of the following has the highest bond dissociation enthalpy?
- F₂
- Cl₂
- Br₂
- I₂
Show answer & explanation
Answer: B. Cl₂
Cl₂ has the highest bond dissociation enthalpy because F₂ has a relatively low bond dissociation enthalpy due to lone pair repulsion.

The van't Hoff factor (i) for a dilute solution of K₃[Fe(CN)₆] is:
- 1
- 2
- 3
- 4
Show answer & explanation
Answer: D. 4
K₃[Fe(CN)₆] dissociates into 4 ions in solution: 3 K⁺ and 1 [Fe(CN)₆]³⁻. Therefore, the van't Hoff factor (i) is 4.
