Answer:
Correct answer is structural formula expanded.
Step-by-step explanation:
A. is wrong.
The molecular formula only show the number of atoms of each element present and the ratio in which they are present. It does not provide any information as regards the bonds whether in its expanded or condensed form.
B. is wrong
While the structural formula will show the inter linkage between the atoms, the condensed structural formula won't provide complete information as regards these interlinkages.
D. is wrong
As established in A above, the molecular formula only provides the number of atoms and their ratios. It does not elucidate the types of bonds present therein.
E. is wrong
The isometric formula, although will elucidate to an extent does not serve the purpose of providing bonding details. It only provides comparisons between isomers.
