1. A Review of General Chemistry

Give the relationship between the following pairs of structures. The possible relationships are:

same compound

constitutional isomers (structural isomers)

cis-trans isomers

not isomers (different molecular formula)

(g) CH₃–CH₂–CH₂–CH₃ and CH₃–CH=CH–CH₃

(h) CH₂=CH–CH₂CH₂CH₃ and CH₃–CH=CH–CH₂CH₃

(i) CH₂=CHCH₂CH₂CH₃ and CH₃CH₂CH₂CH=CH₂

Which of the following statements can be used to prove that carbon is tetrahedral?

a. CH₃Br does not have constitutional isomers.

b. CBr₄ does not have a dipole moment.

c. CH₂Br₂ does not have constitutional isomers.

There are five alkane constitutional isomers with the molecular formula C₆H₁₄. Draw them.

There are nine alkane constitutional isomers with the molecular formula C₇H₁₆. Draw them.

Draw four compounds with molecular formula C₅H₁₀ that have carbon–carbon double bonds but do not have cis–trans isomers.

Draw and label the E and Z isomers for each of the following:

d.

What type of isomerism is indicated by each of the following pairs of molecules? Be as specific as possible.

(b)

Show all possible constitutional isomers of C₅H₁₂O. Label them as functional, positional, or chain isomers.

Draw five more compounds of formula C₄H₆NOCl.
