Which of the following compounds has the highest boiling point? A. n-pentane B. iso-butane C. butane D. neopentane. Acidic hydrogen is present in: A. acetylene B. ethane C. ethylene D. dimethyl acetylene. Identify 'A' in the following reaction:
Understand the Problem
The question is asking which compound has the highest boiling point among a list of hydrocarbons and which molecule contains acidic hydrogen. Additionally, it requests to identify a labeled part in a reaction. This involves knowledge of organic chemistry, specifically properties of hydrocarbons and functional groups.
Answer
n-Pentane has the highest boiling point; acetylene has acidic hydrogen.
The final answer is n-pentane for the highest boiling point and acetylene for the acidic hydrogen.
Answer for screen readers
The final answer is n-pentane for the highest boiling point and acetylene for the acidic hydrogen.
More Information
n-Pentane’s linear structure allows greater intermolecular forces compared to branched alkanes. Acetylene's terminal alkyne makes its hydrogen acidic, unlike other hydrocarbons listed.
Tips
Confusing the role of branching in boiling points is common. Remember, more branching equals lower boiling point.
