For the given compound If π - electron cloud of C 1 –C 2 carbon atoms is perpendicular to the plane of paper, then total number of H-atoms lying in the plane of paper will be-

TestHub · Accepted Answer

allene and cumulene derivatives has alternating π-bonds with perpendicular p-orbitals. Given C1–C2 π-cloud is perpendicular to plane of paper, the orientation alternates along the chain. Due to symmetry, all terminal and alternate carbons keep their hydrogens in the plane. On counting, total 6 hydrogen atoms lie in the plane of paper.
