Find the answer that has correct both the two structures of cis-1-isopropyl-4-methylcyclohexane and their relative stability (stability is indicated with ">" meaning "more stable than").

Replacing the acidic hydrogen of a carboxylic acid with an organic group produces an amide.

What class of amine is found in the analgesic codeine (shown below)?

Give the condensed structural formula for 2-methylpropanoic acid.

In alkene nomenclature "trans" stands for "on the same side" while "cis" means "across".

Which of the following compounds is(are) Z configuration(s)?

What are skew conformations?

What are the possible positions for hydrogen on the chair conformation of cyclohexane?

The common ether used in anesthesia has the IUPAC name ________.

How many chiral carbon atoms can you find in the molecule below?

There are three rules for assigning priorities: Rule 1: A substituent atom of higher atomic number takes precedence over one of lower atomic number Rule 2: If two substituent atoms attached to the stereocenter have the same priority, the atom on the right of a hydrogen atom bonded to chiral carbon is a substituent of higher priority. Rule 3: Double and triple bonds are treated as if they were single, and the atoms in them are duplicated or triplicated at each end by the particular atoms at the other end of the multiple bond. Which rule(s) is/are stated incorrectly?

Different forms of isomerism in organic compounds can be summarized as follows: "Isomers can be constitutional or stereoisomers. Constitutional isomers are further divided in enantiomers and diastereomers."

Which of the following methods are used for the laboratory alkane synthesis? I. catalytic addition of hydrogen to multiple carbon - carbon bonds II. catalytic hydrogenation of aldehydes III. from halogenated hydrocarbons and sodium IV. from alkali metal salts of organic acids and alkali metal hydroxides V. dehydrohalogenation of organic halogen compounds

Which of the following chiral compounds is(are) S enantiomer(s)?

Which of the following four molecules are aromatic?

Which methods can be used to prepare alcohols? I. addition of H₂O to alkenes in the presence of H₂SO₄ II. reacting alkanes with a concentrated solution of MOH III. hydrolysis of alkyl halides IV. methanol can be prepared from CO and H₂ in the presence of a heterogeneous catalyst V. removing one oxygen atom from a carboxylic acid
