Schiff’s test is used to detect aldehydes. Aldehydes react with Schiff’s reagent to give a pink or magenta color, while ketones do not. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
Ref: NCERT Chemistry Textbook for Class XI and XII, Chapter: Relevant Chemistry topic covering principles and examples as per NCERT.
Friedel-Crafts acylation is used to prepare ketones, not aldehydes. This follows from latest NCERT 2026-27 principle explaining the concept clearly for NEET students in simple steps as per rationalized syllabus.
Ref: NCERT Chemistry Textbook - Latest Edition for Academic Session 2026-27 (Rationalized Textbook for Class XI and XII)Topic: Mole concept, atomic structure, chemical formulas like H₂O, CO₂, CH₃CH₂NH₂ and periodic trends.
Pentanal (CH₃CH₂CH₂CH₂CHO), a straight-chain aldehyde, has stronger dipole-dipole interactions than branched isomers like 2-methylbutanal, giving it the highest boiling point.
