Hexane or Heptane?

6/21/2020Where swim lives Hexane is much cheaper so she would like to know if there is a good reason to pay 2-3 times more for Heptane Actually Hexane seems to have an advantage Its boiling point is 69C (for n-Hexane) while that of n-Heptane is 98 4C OTOH Wikipedia says that Heptane is a totally non-polar solvent

Heptane

Heptane (also known as dipropyl methane gettysolve-C or heptyl hydride) is an alkane hydrocarbon with the chemical formula CH 3 (CH 2) 5 CH 3 Heptane has nine isomers The isomer n-heptane (straight-chain heptane) has been selected as the zero point of the octane rating scale It is undesirable in petrol as it burns explosively causing engine knocking as opposed to branched-chain octane

Heptane — Wikipedia Republished // WIKI 2

n-Heptane is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16 When used as a test fuel component in anti-knock test engines a heptane fuel is the zero point of the octane rating scale (the 100 point is a iso-octane) Octane number equates to the anti-knock qualities of a comparison mixture of heptane and isooctane which is expressed as the percentage of

How many isomers do heptane and octane have?

6/4/20071 Start with heptane - this is a straight chain alkane with 7 carbons 2 You are told 2-methyl This means that a methyl group - CH3 - has been grafted onto the second carbon of the heptane That is why it is called 2-methyl heptane 3
