DRAW THE (C2-C3) NEWMAN PROJECTION OF THE MOST STABLE AND LEAST STABLE  3-Methyloctane 2,3,4-Trimethylhexane

Which of the following is the least stable Newman Projection for pentane looking down the indicated bond (C2-C3 bond)? I I H H CH3 H CH₂CH3 CH3 CH₂CH3 HH H H₂CH₂C CH₂CH₂CH3 CH₂ + 1

6. Draw the Newman projection of cis 1,2-dimethyl-4-t-butyl cyclohexane, and place the t-butyl group in its lower energy position. You want your Newman projection to allow you to sight down the 1,2 C-C bond. Can you draw different isomers? Is one more stable? Make models and try twisting them around. 7. Draw all the stereoisomers of 1-bromo-1-iodo-2-methyl 1-butene. Label E/Z and determine any dipole moments.

please draw the most stable conformer of cis-1-ethyl-2-methylcyclohexane as a Newman projection.
