What is the hybridization at each carbon atom in the molecule? write hybridizations starting on the left in molecule?

Hybridization is a model that endeavors to remedy the limitations of simple valence bond theory because of its inadequacy in explaining bonding & structure of many covalent species that was proposed by G. N. Lewis. Hybridizations starting on the left in molecule are sp2, sp2, sp3, sp, sp, sp3.
