The most common stereocenters are chiral centers (such as asymmetric carbon atoms) and the double-bonded carbon atoms in cis-trans alkenes. A chiral center consists of an atom holding a set of ligands (atoms or groups of atoms) in a spatial arrangement which is not superposable on its mirror image.ost chiral molecules have a chiral carbon, though the presence of a chiral carbon does not necessarily make a molecule chiral (see meso compound). A chiral carbon is often denoted by C*. If the carbon is chiral, it follows that: 1  the carbon atom is sp 3 -hybridized;
Past the inca tunnel, a gentle climb will take you to the third pass at 12139 feet above sea level (3700 masl), offering incredible views of several snow capped peaks including Salkantay (20574 ft./6271m) and Veronica (18865 ft./5750m).
A massive channelization program began in 1911, and by 1917 the main Kankakee channel was straight. The width of the main channel now varies from 75 to 180 feet with an average depth of 4-5 feet. The Kankakee's average fall is approximately 1 foot per river mile and flow is generally at 3-4 miles per hour.
