condensed structural diagram
Answer:
shorthand way to show an organic molecule's structure in a
single line of text, listing atoms in order and using
parentheses for branches or repeated groups
Question:
complete structural diagram
Answer:
similar to Lewis structure. explicitly displays all atoms,
covalent bonds (as lines or pairs of dots), and lone pairs
within a molecule to show precise connectivity

linear structure diagram
Answer:
each line is an intersect of carbons
,Question:
