Question

What is the Lewis Structure for iodoethane (`C_2H_5I`)?

Answer 1

`H_3C-CH_2I`

Explanation:

Around each hydrogen there is `1` electron; around each carbon there are `6` electrons, `4` of which are involved in covalent bonds; around iodine, there are `"7 valence"` electrons, one of which is involved in the `C-I` bond. Each atom is thus neutral.
