Disrotatory vs conrotatory

Webfollowed disrotatory IRC motion and 52/120 (43%) followed non-IRC conrotatory motion to the allyl radical. In these trajectories there was about 30-50 fs delay between rotation of each methylene group. Somewhat germane to this work, Hase suggested that a larger reaction coordinate translational energy can favor disrotatory motion. WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer. Question: Is the following electrocyclic reaction conrotatory or disrotatory? conrotatory disrotatory This is a mixture of conrotatory and disrotatory. This cannot be determined without more information.

An electrocyclic reaction can either be classified as conrotatory or disrotatory based on the rotation at each end of the molecule. In conrotatory mode, both atomic orbitals of the end groups turn in the same direction (such as both atomic orbitals rotating clockwise or counter-clockwise). In disrotatory mode, the atomic orbitals of the end groups turn in opposite directions (one atomic orbital turns clockwise and the other counter-clockwise). The cis/trans geometry of the final prod… WebIn conrotatory, both atomic orbitals of the end groups turn in the same direction either both rotating in clockwise or counte ….
