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).
After approximately 6.5 miles on the trail, you will come to the Barr Camp. If itâs a dry year, it maybe your first opportunity for water since the trailhead. Continuing from the Barr Camp, itâs approximately 5.5 miles to the summit. After reaching the tree line, the trail starts to increase in elevation. Donât be fooled, its tougher than you think. After finishing all of the switchbacks past huge boulders, you will reach the summit (14,110 feet). Take some money with you, there is a place to eat and get souvenirs if you desire. After reaching the summit, you should either have planned for a hike down or have someone pick you up.
