Please give a short, concise explanation of why cyclopentane puckers and cyclohexane form a chair rather than lying flat.

Why does propanal have a Higher boiling point than butane ?

Draw diagrams showing how isopropyl alcohol, ethylene glycol and glycerol can hydrogen bond to themselves. Draw the structure of ethanol, 1-hexanol, cyclohexanol, glycerol, benzyl alcohol, phenol and salicylic acid.   Draw the resonance structure of phenoxide ion.

Dimethyl ether and ethanol have the same molecular mass. Dimethyl ether is a gas at room temperature, and ethanol is a liquid at room temperature. Explain these observations.

What is the difference in bonding and in general molecular formula between an alkene and a cycloalkane with the same number of carbon atoms?

How does the structure of a cycloalkane differ from that of a straight-chain or branched-chain alkane?

A semi-truck loaded with cyclohexane overturns during a rainstorm, spilling its contents over the road embankment. If the rain continues, what will be the fate of the cyclohexane?

As stated in Section 11-9, the wax found in apple skins is an unbranched alkane with the molecular formula C^H^. Explain how the presence of this alkane in apple skins prevents the loss of moisture from within the apple.

Instead of using the ending “ol,” an OH can be treated like a substituent or halogen using the term“hydroxyl.” For example, hexane-2,4-diol can be called 2,4-dihydroxyhexane. Write anequivalent name for 1,2,3-cyclohexanetriol using the term “hydroxyl.”
