Best Answer

In structural isomers, the atoms and functional groups are joined together in different ways.

Text definition:

Two or more substances composed of the same elements with the same proportions but differ in properties due to different arrangements of atoms.

For more details see the Web Links to the left.

First of all in organic chemistry you are always dealing with a string of Carbon atoms and an isomer both samples have the same amount of carbon atoms but have a different molecular structure an example would be Pentane and 2-Methyl Butane.

Is dimethyl ether a structural isomer?

Yes, dimethyl ether is a structural isomer of ethanol. They both have the same molecular formula (C2H6O) but different structural arrangements.


Is H2O an isomer?

No, H2O (water) is not considered an isomer. Isomers are molecules with the same molecular formula but different structural arrangements. Water does not have other structural arrangements that would make it an isomer of itself.


Why is glucose a structural isomer?

A structural isomer is when molecules have the same formula, but a different structure. Glucose is a structural isomer because Pyruvate and Ribose have the same formula (CH2O), but have a different number of carbons, hydrogens and oxygens: C3H6O3 - Pyruvate C5H10O5 - Ribose C6H12O6 - Glucose Hope this helps! :)


Is aldehyde structural isomer of ketone?

Yes, aldehyde is a structural isomer of a ketone. Both aldehydes and ketones contain a carbonyl group, but in aldehydes, the carbonyl group is located at the end of the carbon chain, while in ketones, it is located within the carbon chain.


Is Glucose and Fructose a geometric isomer?

Nope. They are structural isomers.


Is isobutanol a structural isomer of 1- butanol and 2-butanol?

Yes, isobutanol is a structural isomer of both 1-butanol and 2-butanol. Isobutanol has a branched structure, while 1-butanol and 2-butanol have linear structures.


What is the structural isomer of 2-methylbutane?

The structural isomer of 2-methylbutane is pentane. Both 2-methylbutane and pentane have the same molecular formula, C5H12, but differ in the arrangement of carbon and hydrogen atoms.


What functional group or molecule maybe structural isomer of a ketone?

An aldehyde is a functional group that is a structural isomer of a ketone. Aldehydes differ from ketones by having a carbonyl group at the end of a carbon chain, while ketones have the carbonyl group located within the chain.


Is cyclo-hexane an isomer of hexane?

Yes, cyclohexane is a structural isomer of hexane. Cyclohexane is a cyclic compound with a ring of carbons, while hexane is an acyclic compound with a chain of carbons.


A carbon molecule that has a different arrangement of atoms is know as?

An isomer. Isomers have the same molecular formula but different structural arrangements, giving them distinct chemical and physical properties.


What is the structural isomer of C8H18 with the lowest boiling point?

The structural isomer of C8H18 with the lowest boiling point is 2,2,4-trimethylpentane. This isomer has a lower boiling point compared to other C8H18 isomers due to its more compact structure, which results in weaker intermolecular forces and easier vaporization.


Is CO2 an isomer?

No, CO2 is not an isomer. Isomers are molecules that have the same molecular formula but different structural arrangements of atoms. CO2 is a linear molecule composed of one carbon atom and two oxygen atoms bonded in a straight line.
