Chapter 24: Problem 81

Draw the condensed structural formulas for two different molecules with the formula \(\mathrm{C}_{3} \mathrm{H}_{4} \mathrm{O} .\)

Short Answer

Expert verified
Two different molecules with the formula \(\mathrm{C}_{3} \mathrm{H}_{4} \mathrm{O}\) can be represented by the condensed structural formulas: 1. \(CH_2=C(OH)CH_3\), which forms a double bond between one of the carbon atoms and the oxygen atom, and single/double bonds between carbon-carbon atoms. 2. \(CH_3C(O)CH\), which forms a triple bond between carbon atoms and a double bond between the middle carbon atom and the oxygen atom.

Step by step solution

01

Identify the possible atom arrangements

To create molecules with the formula \(\mathrm{C}_{3} \mathrm{H}_{4} \mathrm{O}\), we must connect three carbon atoms, four hydrogen atoms, and one oxygen atom. We can start by creating different types of bonds between the carbon and oxygen atoms. In each case, we'll need to think about possible hydrogen placements.
02

Draw the first molecule

Let's start by creating a molecule with a double bond between one of the carbon atoms and the oxygen atom. We can place the rest of the hydrogen atoms to complete the molecular formula. The condensed structural formula for this molecule is given by: \[ CH_2=C(OH)CH_3 \] In this molecule, carbon-carbon atoms are connected via single and double bonds. The oxygen atom forms a single bond with the middle carbon atom, while the two remaining carbon atoms are each bonded to two hydrogen atoms.
03

Draw the second molecule

Now, let's create another molecule that involves an arrangement with a triple bond. We can place the rest of the hydrogen atoms accordingly to fulfill the molecular formula. The condensed structural formula for this molecule is given by: \[ CH_3C(O)CH \] In this molecule, carbon-carbon atoms are connected via single and triple bonds. The oxygen atom forms a double bond with the middle carbon atom, while one carbon atom is bonded to three hydrogen atoms, and the other carbon atom is bonded to one hydrogen atom. These two condensed structural formulas represent different molecules with the same molecular formula \(\mathrm{C}_{3} \mathrm{H}_{4} \mathrm{O}\).
