what would the chemical equation look like for each IUPAC name 4-phenyl-2-pentyne b. 2-phenyl-3-pentyne c. 3-phenyl-4-pentyne d. 2-phenyl-4-pentyne
Do you mean structural formula? We can't draw those things on the board. I suggest you go to google.com and type in the compound. With any luck at all you can find a site that has the formula drawn (although I tried the first one and had no luck).
