Arrange the solutions in order of increasing basicity: CH3NH3Br, KOH, KBr, KCN, C5H5NHNO2.
Verified step by step guidance1
Identify the nature of each compound: CH3NH3Br is a salt of a weak base (CH3NH2) and a strong acid (HBr), KOH is a strong base, KBr is a neutral salt, KCN is a salt of a weak acid (HCN) and a strong base (KOH), and C5H5NHNO2 is a salt of a weak base (C5H5N) and a strong acid (HNO2).
Determine the basicity of each compound: CH3NH3Br will be slightly acidic due to the presence of CH3NH3+, KOH is strongly basic, KBr is neutral, KCN is basic due to the presence of CN-, and C5H5NHNO2 will be slightly acidic due to the presence of C5H5NH+.
Arrange the compounds based on their basicity: Start with the most acidic (least basic) and move to the most basic.
Consider the neutral compound (KBr) as having no basicity, placing it between acidic and basic compounds.
Order the compounds from least basic to most basic: CH3NH3Br, C5H5NHNO2, KBr, KCN, KOH.
