(a) Draw a Lewis structure for each of the following species: CH31; CH4; CH32; CH2; CH221; CH222. (b) Identify each as a radical or not.

After I drew out the Lewis Structures and counted the valence electrons, they all have an even number of electrons and all electrons are paired. Is the answer to question b) no for all of the species?

[nicolely2F]

Correct, none are radicals.

[Nick Fiorentino 1E]

Yes, only species with odd numbers of electrons are radicals (ex CH3 has 7 valence electrons so it is a radical)

[AnayaArnold_3L]

radicals are only present when there is an odd number of electrons.

[Jack Riley 4f]

Radicals only exist when there are an odd number of valence electrons. None of these examples have an odd number so none are radicals

[605208780]

Yes. There are only radicals when there is an odd number of electrons.

[Jasmine Vallarta 2L]

radicals only occur when there is an odd number of e-

[BritneyP- 2c]

none of them are radicals.
