SUMMARY

Cyclopropane (C3H6) undergoes a rearrangement to form propane (C3H8) at a rate of 0.25 mol/s. The chemical formula for propane is derived from the general alkane formula C(n)H(2n+2), where n represents the number of carbon atoms. For propane, n equals 3, resulting in the formula C3H8. This discussion emphasizes the importance of understanding alkane structures in basic chemistry.

Cycloppropane (C3H6) disappears and rearanges to form propane and another compound at rate of .25mol/s

Homework Equations

How do you know what the chemical formula for propane is? in order to find the rate propane is being produced?

The Attempt at a Solution

Propane is one of the alkanes, which are usually memorized in basic chemistry classes, but the formula is C(n)H(2n+2), where n denotes the number of carbons. A carbon chain will have 2 hydrogens for each carbon, plus an additional one on each terminal carbon. For propane, n=3 as mentioned in the question (cyclic and non-cyclic will never change in number of carbons). Therefore 2n+2=8. The formula is C3H8.

You can practice this using any alkane. Butane is C4H10. Decane is C10H22.
