WebMar 3, 2016 · If you are comparing CH3 (methyl) to CH2 you are invoking that that CH2 is also connected to something else, and if it is connected to another carbon it would get higher priority (think comparing CH3 to CH2C, CH2C is bigger). So if an alkene has a hydrogen, methyl, ethyl, and propyl, propyl and ethyl are the highest priority …
