Answer all please! Thank you in advance. .22-76 Many of the condensations we have studied are reversible. The reverse reactions are often given the prefix retro-, the Latin word meaning "backward." Propose mechanisms to account for the following reactions. (a) Y CH; H . = CHC-(CHỊ) -CHO (b) TICH CHH ТСН. (retro-aldol and further condensation) OH (retro-aldol) Sca-es + H.C=CH-CN CH HOH OCH, CHOH COOCH (retro-aldol and crossed Claisen) CN (retro-Michael)
