Physical Properties and Nomenclature
Explore the boiling points, solubility, hydrogen bonding, and IUPAC naming rules for aldehydes, ketones, and carboxylic acids.
Why this shows up in the exam
Expect questions on trends, structure-property relationships, and correct naming.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Given below are two statements. Statement-I : The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole-dipole interactions. Statement-II: The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of H-bonding. In the light of the above statements, choose the most appropriate answer from the options given below:

More challenging4 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
Consider the compound: CH3-CH(COOH)-CH=C(CH3)-CHO. What is its correct IUPAC name?
