🔥SURE SHOT MCQ's from Isomerism🔥 | NEET 2026 | NEET RANKERS BATCH | HSP SIR |

Описание: Isomerism is a fundamental organic chemistry concept for NEET, covering compounds with the same molecular formula but different structures or spatial arrangements. Key types include Structural Isomerism (chain, position, functional, metamerism, tautomerism) and Stereoisomerism (geometrical/optical). These isomer types differ in physical/chemical properties due to connectivity or spatial orientation.

Key Aspects of Isomerism for NEET:

Structural Isomerism: Involves different bonding connectivity.
Chain: Different carbon skeleton branching (e.g., pentane vs. isopentane).
Position: Functional group or substituent located at different positions on the same chain (e.g., 1-chlorobutane vs. 2-chlorobutane).
Functional: Same formula, different functional groups (e.g., alcohols vs. ethers, aldehydes vs. ketones).
Metamerism: Different alkyl groups attached to the same functional group (e.g., ethers).
Tautomerism: Rapid equilibrium between isomers, typically keto-enol forms.
Stereoisomerism: Same connectivity, different 3D spatial arrangement.
Geometrical (Cis-Trans): Restricted rotation (double bonds or rings) creates stereoisomers.
Optical: Non-superimposable mirror images (enantiomers) due to chiral centers.
Conformational Isomerism: Rotamers generated by rotation around a single bond (e.g., staggered/eclipsed in alkanes).
