which of the following most nearly describes the geometry of the methyl radical?


Step 1 : Introduction to the question "which of the following most nearly describes the geometry of the methyl radical? "



The molecular geometry of the methyl radical is quasi-trigonal planar, although the energy cost of distortion to a pyramidal geometry is small. Substitution of hydrogen atoms by more electronegative substituents leads to radicals with a pyramidal geometry, such as the trifluoromethyl radical, CF3.



Step 2 : Answer to the question "which of the following most nearly describes the geometry of the methyl radical? "



trigonal planar, bond angle 120°: Methyl was discovered in interstellar medium in 2000 by a team led by Helmut Feuchtgruber who detected it using the Infrared Space Observatory. It was first detected in molecular clouds toward the centre of the Milky Way.


Step 3 : Other interesting facts related to the question "which of the following most nearly describes the geometry of the methyl radical? "



Methyl radicals can be obtained by pyrolysis of azomethane, CH3-N=N-CH3, in a low-pressure system.
