Draw all the isomers that have molecular formula c5h11br. (hint: there are eight.) give the systematic name for each of the isomers. give a common name for each isomer that has a common name. how many of the isomers are primary alkyl halides? how many of the isomers are secondary alkyl halides? how many of the isomers are tertiary alkyl halides?

The 8 isomers are drawn in the image:

1) 1-bromopentane

2) 2-bromopentane

3) 3-bromopentane

4) 1-bromo-2-methylbutane

5) 1-bromo-3-methylbutane

6) 2-bromo-2-methylbutane

7) 2-bromo-3-methylbutane

8) 1-bromo-2,2-dimethylpropane

1), 4), 5) and 8) are primary alkyl halides (alkyl bromides).

2), 3) and 7) are secondary alkyl halides (alkyl bromides).

6) is a tertiary alkyl halide (alkyl bromide).

Explanation:

Primary alkyl halides have the halogen (bromine) attached to a primary carbon, that is, a carbon that is attached to a single carbon (and two hydrogens).

Secondary halides have the halogen (bromine) attached to a secondary carbon, that is, a carbon that is attached to two carbons (and a hydrogen).

Tertiary halides have the halogen (bromine) attached to a tertiary carbon, that is, a carbon that is bonded to three carbons (and no hydrogen).

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
