The structure of C is to be predicted. Concept introduction: In Wittig reaction, aldehyde can be directly converted to alkene using triphenyl phosphonium ylide. The geometry of the alkene formed, depends on the stability of the ylides. The addition of H 2 in presence of catalyst is known as catalytic hydrogenation reaction. This is a syn addition. Alkene is reduced to alkane .
