Question

CF3 freeradical has pyramidal shape why? Explain.

Answer 1

Hello friend

Since in F is highest electro negative element, if CF3 is in sp2 the structure is planar, which leads to the maximum angle of 90 degree between electron on carbon and the C-F bond. While in tetrahedral the angles increases to almost 109 degrees. Hence stability increases. Hope this clears your doubt.
