Question

Draw structures for all constitutional isomers with the molecular formula c2h5cl

Answer 1

Two constitutional isomers exist for C2H5Cl: 1-chloroethane (ethyl chloride) and 2-chloroethane (chloroethane), with chlorine bonded to different carbon atoms in each isomer.

Step-by-step explanation:

The student has asked to draw structures for all constitutional isomers with the molecular formula C2H5Cl, which is a chemical exercise focusing on understanding the different ways in which atoms can be rearranged in space to create molecules with the same molecular formula but different structures.

There are actually only two constitutional isomers with the formula C2H5Cl. These isomers are:

• 1-chloroethane (ethyl chloride): CH3CH2Cl
• 2-chloroethane (chloroethane): CH3ClCH3

In these structures, the chlorine atom is bonded to different carbon atoms, resulting in molecules that have different physical and chemical properties.

Answer 2

Constitutional isomers are compounds that have the same molecular formula but different connectivity.

To determine whether two molecules are constitutional isomers, just count the number of each atom in both molecules and see how the atoms are arranged.
If both molecules have the same count for all of the different atoms, and the atoms are arranged in different ways (i.e. their connectivity is different), then they will be constitutional isomers.

In this case C2H5Cl will not have any constitutional isomer. Because you can attach the Cl on first carbon or second carbon, both structure will be same. There will only exist one structure. Figure is attached
