Chemistry - CHEMICAL BONDING Question with Solution | TestHub

conjugated cumulene hydrocarbon contains a mix of sp, sp², and sp³ carbons, and its π-bonds are arranged in alternating perpendicular planes. Statements (A), (B), and (C) are consistent with hybridization and planar constraints. However, statement (D) is incorrect because not all carbon atoms can lie along a single axis due to branching and perpendicular π-systems. Hence maximum 7 carbons cannot be collinear.
