​

Answer 1

Vollhardt, K. Peter C. Organic chemistry: structure and function. Neil Eric Schore. New York. p. 73. ISBN 1-319-07945-8. OCLC 1007924903. A Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from a Lewis base to form a Lewis adduct

AND YOUR PROPER ANSWER

All cations are Lewis acids since they are able to accept electrons. Examples include copper (Cu2), iron (Fe2+ and Fe3+), and hydrogen ion (H+). An atom, ion, or molecule with an incomplete octet of electrons can accept electrons

Answer 2

Answer + Explanation :
