Arrange the given compounds in increasing order of their basicity. Provide a suitable reason for your answer.

• A. (Low basicity) HCOO⁻ < ⁻OH < CH₃CH₂O⁻ < ⁻NH₂ < ⁻CH₃ < Br⁻ < NO₃⁻ (High basicity)
• B. (Low basicity) Br⁻ < NO₃⁻ < HCOO⁻ < ⁻OH < CH₃CH₂O⁻ < ⁻NH₂ < ⁻CH₃ (High basicity)
• C. (Low basicity) Br⁻ < NO₃⁻ < CH₃CH₂O⁻ < ⁻NH₂ < HCOO⁻ < ⁻OH < ⁻CH₃ (High basicity)
• D. (Low basicity) Br⁻ < NO₃⁻ < HCOO⁻ < ⁻NH₂ < ⁻CH₃ < ⁻OH < CH₃CH₂O⁻ (High basicity)

Answer: (B)
