Draw the planar (Haworth) structure for cis-1-ethyl-2- methylcyclohexane. (b) Draw the two ring - flipped chair conformations. (c) Circle the more stable chair conformation (circle both if they are equal in energy).  Draw the Haworth structure and the two ring-flipped conformations of 1, 2, 4- trimethylcyclohexane (Compound D) on the frames below, b) Circle the more stable chair conformation (circle both if they are equal in energy). Haworth Structure

Consider methyl ethyl ketone (CH,COCH,CH;) and diethyl ether (CH,CH,OCH,CH;). Which is more soluble in water and why? The ketone is more soluble in water because it contains less than six carbons. The ether is more soluble in water because a carbonyl is less polar than an ether. The ketone is more soluble in water because a carbonyl is more polar than an ether. The ether is more soluble in water because it is an unbranched chain and the ketone carbonyl creates a branching segment. The ether is more soluble in water because it is contains less than six carbons.
