cycloalkane

A special structure in organic chemistry containing single carbon bonded ring(s); cyclic alkanes. A way to imagine a cyclic alkane is to take a simple alkane chain, CH3(CH2)nCH3, and have the two terminal methyl groups meet, bending the chain, creating a ring. The shape of ring is completely dependent on the number of carbon atoms the ring contains. Example: cyclopropane (three carbons, therefore three vertices) is a triangle. Cyclohexane (6) would be a hexagon (on a plane, in space however the joints are kinked).

cyclopropane, cyclobutane, cyclohexane, cycloalkanes

cyclomute

verb:

to travel back and/or forth regularly by bicycle, tricycle, unicycle or similar human powered vehicle (as between where you are and where you want to be)

Lacking the desire to climb in to a motorized vehicle, Yehuda decided to cyclomute to work. He was laughed at by the 'regular' commuters... who were stuck in traffic.

Cyclopentadiene

An hydrocarbon compound that is basically violating being a hydrocarbon. Its pKa value is only 16, making it as acidic as water.
Its structure is a cyclopentane ring with 2 double bonds.

The reason for cyclopentadiene to be such acidic is because of its ionic structure. It has an aromatic anionic structure, making it extremely stable.
