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).
Yosemite National Park. According to the National Park Service, the hike takes 10-12 hours to complete round-trip (http://www.nps.gov/yose/planyour...). But of course your time could be very different, here's the details: The trail route is 14-16 miles, call it 15 taking the JMT up and the Mist Trail on the return.
