Question

Which of the following compounds can be labeled as Lewis acids. There may be more than one answer.

a. BBr3
b. CH3CH2OH
c. (CH3)3C+
d. Br—

Answer 1

Step-by-step explanation:

According to Lewis, acids are the species which readily accept electrons. Whereas bases are the species which donate electrons to electron deficient or electropositive ions.

Out of the given options, boron of
`BBr_(3)` and carbon of
`(CH_(3))_(3)C^(+)` contain sextet of electrons. This means that they have accepted electrons from the combining atoms.

Thus, we can conclude that out of the given options
`BBr_(3)` and
`(CH_(3))_(3)C^(+)` compounds can be labeled as Lewis acids.
