What is the minimum number of hybridized carbon atoms that must be attached to different substituent — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

Cycloalkanes show Geometrical Isomerism (GI) due to the restricted rotation around the rigid single bonds of the ring. For GI to exist, a minimum of two separate $sp^3$ hybridized carbons in the ring must each be bonded to two different atoms or groups, allowing for 'cis' (same side) or 'trans' (opposite side) spatial arrangements.
