Question

What is the difference between expanded and condensed structural formulas.

Answer 1

Hint: In order to solve this question we will first learn the real structure or we can say it shows all the bonds that are present in that atom while the condensed structure shows only the molecular formula of the compound.

Complete step by step answer:
For solving this question we will first understand the Condensed structural formulas so the condensed structural formula shows the order of atoms like a structural formula but are written in a single line to save space and make it more convenient and faster to write out. Condensed structural formulas are also helpful when showing that a group of atoms is connected to a single atom in a compound.
A structural formula tells us which atoms are in a molecule. It also shows us how they connect to each other.
There are different types of structural formula. The least complicated structural formula tells us which atoms connect to which.
A condensed structural formula is a system of writing organic structures so we can type them in a line of text.
It shows all atoms, but omits the vertical bonds and most or all the horizontal ones.
The condensed structural formulas of ethane, propane, and ethanol are
\[C{H_3}C{H_3}\], $C{H_3}C{H_2}C{H_3}$, and $C{H_3}C{H_2}OH$
A condensed structural formula uses parentheses to show that polyatomic groups within a formula are attached to the nearest non-hydrogen atom on the left.
So the condensed structural formula of propan-2-ol is \[C{H_3}CH\left( {OH} \right)C{H_3}\]
It also uses parentheses to show that polyatomic groups at the beginning of a formula are attached to the atom on the right.
So we could also write the condensed structural formula of propan-2-ol as\[{(C{H_3})_2}CHOH\]
And we could write the condensed structural formula of hexane as \[C{H_3}C{H_2}C{H_2}C{H_2}C{H_2}CH\].

Note: While solving these types of questions we should keep in mind that these are the same compounds if the molecular mass is the same but one thing should be kept in mind that if some of the compounds the orientation is changed the properties may change either the molecular mass is same.
