2. Phenol (C6H5OH) has a Ka of 1.6*10-10. Starting with a 100.0 mL solution that is 0.300 M phenol, state how you would make a buffer with pH 10.00 a. By adding solid sodium phenolate (NaC6H5O)

l dont know l am s sorry

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
