Straight chain isomers have higher boiling points, so the more branched the isomer the lower the boiling point.

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

In organic chemistry, alkanes such as C8H18 have structural isomers. The more these isomers are branched the lower the boiling point is. The reason for this, is that un-branched alkanes have a higher mass area, they are more likely to have more potential points of attachments for other atoms or molecules which would then raise intramolecular forces thus increasing boiling points. The structural isomer of C8H18 that has the boiling point is systematically known as 2,2,3,3-tetramethylbutane.


Why does n butane has high boiling point?

Straight chain isomers have higher boiling point than their more compact isomers because there are fewer dispersion forces in the symmetrical molecule The dispersion forces of straight chain alkanes increase with molecular weight. Stronger intermolecular forces develop in long chains, and the boiling point and melting point increase with MW.


Why are CH3CH2COOH and CH3CHOHCHO optical isomers?

These are not optical isomers they are functional group isomers a subcategory of structural isomers.


Nitration of phenol can be accomplished by using nitric acid at room temp. but the result is a mixture of p-nitrophenol and o-nitrophenol. the isomers can be separated by steam distillation. WHY?

This is because the two isomers have different boiling points and one of which falls under 100 degrees celsius (2-nitrophenol). hence the first to evaporate out is the 2nitrophenol and the rest will be 4nitrophenol.

Can two isomers be differentiated by their boiling point?

yes they can be differentiated by there boiling point . now u would have a question that if they are made up of the same things then why ? it is because that they have different stucture which makes the difference

How does the number of carbon atoms in a hydrocarbon atom affect its boiling point?

The more is the number of carbons in the alkane, the more is its boiling point.REASON:- As the number of carbon increases, the becomes the molecular mass. And the more is the molecular mass, the greater becomes the surface area which increases the van der Waal force of intermolecular attraction thereby increasing the boiling point of the alkane.NOTE:- Among isomers (of the same alkane), the structure which have more # of side chain has less BP because more the # of side chains are present, more will the structure will be closer to the shape of a sphere, therefore will have smaller surface area.-by spd831
