1. Draw the Neman Projection of the following Promane descriptions Newman projection for most stable Newman projection for least stable conformation conformation 2. Draw the Newman projections for butane looking down the C2-C3 bond through a full 360 degree rotation. Start with the anti-staggered Newman projection then draw and label each Newman projection (staggered, eclipsed, gauche, anti-staggered, fully-eclipsed) for every 60 degrees of rotation Newman projection for most stable Newman projection for second-most stable conformation Conformation Newman projection for least...
Conformations of Alkanes and Cycloalkanes 1) Draw a Newman projection of the anni conformation of 1.2-dichloroethane che conformation of 1.2-dichloroethane 2) Draw a Newman projection of the 5) Sight along the C2-C3 bond of 2-methylbutane and draw each of the staggered conformations 4) Arrange the following conformations from lowest to highest energy. CH CH 5) Circle the Most stable conformation of the molecule shown below. н сн, YI 6) Circle the Most stable conformation of the molecule shown below.
Sighting along C2-C1 bond of 2-methylpropane and C2-C3 of 2-methylbutane a. Draw a Newman projection of the most stable conformation of each compound b. Draw a Newman projection of the least stable confirmation of each compound
Draw a Newman projection for the lowest-energy conformation of 2,3-dimethylbutane about the C2C3 bond.
Draw a newman projection of the most stable staggered conformation of 4-bromo-3-methylheptane looking down the C3-C4 bond. Then draw a newman projection of the least stable staggered conformation of the same compound looking down the C3-C4 bond - label where different type(s) of strain occur making this conformation less stable? I have no idea how to do this so step by step would be perfect. Thank you.
1. a) Calculate the lowest energy conformer of 2-methylpropane. Use as many calculations as necessary. Then, draw the Newman projection looking down the C1-C2 bond and draw it with 3-D geometry. b) Calculate the lowest energy conformer of 2-methylbutane. Use as many calculations as necessary. Then, draw the Newman projection looking down the C2-C3 bond and draw it with 3-D geometry.
3. Draw butane in wedge and dash depiction, sawhorse depiction and in its Newman projection looking down the 2.3 bond. Show eclipsed, gauche and anti forms. 4. Draw all Newman projections of 2-methylhexane showing eclipsed, gauche and anti forms. Rotate about the 3.4 carbon-carbon bond and watch what happens to the Draw a potential energy diagram for the rotation about the 3,4 carbon- carbon bond plotting Potential Energy versus Torsion Angle.
