2-ethyl propane is incorrect nomenclature as - (Quiz 13 L3 Ch5) a) Branches are not written in alphabetical order b) the root chain is not the longest carbon chain c) The numbering does not start from the nearer side to the branch d) numbering does not start from the correct side which gives the branches the least possible summation

Did you know that the correct name for 2-ethylpropane is actually 3-methylpentane? That’s because the longest continuous chain has five carbons—hence "pentane"—and the "ethyl" substituent is too far down to be correctly called 2-ethyl. Proper nomenclature is all about identifying the longest chain first! When naming compounds in organic chemistry, remember this handy tip: start numbering from the end closest to the first substituent. This ensures that you minimize the numbers in your name and gives the most accurate description of your compound. A common mistake is to overlook this and end up with confusing names that lack clarity in describing the compound's structure. Keep it simple and structured!
