Draw all the possible isomers with the molecular formula C₄H₉Cl, and determine how many are:

a. Primary (1°) alkyl halides.

b. Secondary (2°) alkyl halides.

c. Tertiary (3°) alkyl halides.

Consider the following compound:

Write an IUPAC name for this compound and classify this compound as a primary, secondary, or tertiary alkyl halide. Additionally, write a common name (if possible).

Provide the condensed and skeletal structures for 6,6-dichloro-2-methylnonane.

Draw all the cyclic isomers of C₄H₇Br and give the systematic names for each of them.

Write each structure's IUPAC name.

Write the IUPAC names of the following compounds. Provide the line-angle structure if a condensed structure is given and the condensed structure if a line-angle structure is shown.

For the given molecule:

What are its IUPAC and common names? Classify the alkyl halide type (methyl, primary, secondary, or tertiary alkyl halide).
