Please help me with this question

4. Draw a chair conformation of the following molecules. Ring flip your original chair, and circle the more stable conformation. cis-1,2-dimethylcyclohexane trans-1-tert-butyl-3-ethylcyclohexane cis-1,4-diisopropylcyclohexane cis-1-butyl-3-methylcyclohexane

Why cis 1,3-diisopropylcyclohexane locked into one conformation while trans 1,3- diisopropylcyclohexane freely flips from one chair conformation into the other?

what is the chair conformed and the ring that represents it? which chair conformation is the most stable?

QUESTION 22 Choose the Newman projection that shows the most stable conformation with respect to the bond marked with the arrow. CH3 CH3 H.
