The Lewis structure of allene is Which of the following statements correctly gives answers for all 3 parts: (a) Is the molecule planar? (b) Does 1, 3 - dichloro propadiene show geometrical isomerism? (c) Is the molecule 1, 3 - dichloro propadiene polar?

Step-by-step solution

Hybridization of central carbon is sp and two of its unhybridized p -orbitals are involved in π - bonding. Also p - orbitals at an atom are orthogonal (at 90 ο angle), the two π - bonds at central carbon are also orthogonal. Let these p - orbitals, involved in π - bonding, at central carbon be p y and p z , then Hybridization at the terminal carbons are both sp 2 . The two p - orbitals involved in sp 2 hybridization are p x and p y at left terminal and p x and p z at right terminals. Therefore, the three s p 2 hybr
