(S)-Octan-2-ol Pyridine NaNg ) LIAIHA C MEOH II) H2O

2. Draw the two chair conformations of 3-tert-utyl-1-methylcyclohexanol and estimate the amount of strain energy in each. Which conformation is favored?

Draw one stereoisomer structure of cis-diethylcyclohexane.

Define the degree of unsaturation ?

2. How many units of unsaturations does a compound with the formula C25H40Cl4 have? 3. Give the name of this compound, including stereochemistry if relevant: (CH3)3CCH₂CI

Draw the highest and lowest energy conformations. In cases where two or three conformations are degenrate, choose only one as your answer. Use Ch2Ch3, H and Ch3 for the structure.

Diels–Alder reaction of a monosubstituted diene (such as CH2=CH–CH=CHOCH3) with a monosubstituted dienophile (such as CH2=CHCHO)gives a mixture of products, but the 1,2-disubstituted product oftenpredominates. Draw the resonance hybrid for each reactant, and use thecharge distribution of the hybrids to explain why the 1,2-disubstitutedproduct is the major product.

just problem 5.26 please

Draw a structural formula for 2-cyclopenten-1-ol. • Show stereochemistry only if given in the name. • If a group is achiral, do not use wedged or hashed bonds on it. • In cases where there is more than one answer, just draw one.
