Vedclass · Answer

(B) Lewis base is a substance that can donate a lone pair of electrons.$1$. $BF_3$: Boron has an incomplete octet ($6$ electrons),making it a Lewis acid.$2$. $PF_3$: Phosphorus has $5$ valence electrons,$3$ are used in bonding with $F$ atoms,leaving one lone pair on the $P$ atom. This lone pair can be donated,making $PF_3$ a Lewis base.$3$. $CF_4$: Carbon has a complete octet and no lone pairs,making it chemically inert in this context.$4$. $SiF_4$: Silicon has empty $d$-orbitals,allowing it to accept electron pairs,making it a Lewis acid.Therefore,$PF_3$ is the correct answer.

Which of the following fluoro-compounds is most likely to behave as a Lewis base?
