Beta, listen...you are asking the wrong farmer. We learned this in CBSE, not ICSE, and my son had to teach me the new names. Pick the longest carbon chain like choosing the straightest row for sowing, number it so the branches get the smallest number—that's your lowest locant. For isomers, just remember like my neem and ber trees: same seeds, different shape.
It makes me sigh, because my old books are useless now, like my field map before the developers came. But still, we learn. I hear it on the radio sometimes, between the weather and the songs.
