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: The South Kaibab Trail is 6.8 miles to Bright Angel Campground and the Bright Angel Trail is 9.3 miles. It will take most hikers between 4 and 5 hours to get to the campground on either trail. Oddly enough, very few people ask how long the return hike will take. The return hike may take twice as long, though 7 to 8 hours seems to be average.
