Lewis acids among the following are

\begin{array}{cccccccccccccccccccc} {\left( {\text{a}} \right)\,\,CC{l_4}}&{\left( {\text{b}} \right)\,\,SiC{l_4}}&{\left( {\text{c}} \right)\,\,Ge{F_4}} \end{array}

View answer and explanation

Correct option: B

b & c

Option B (b & c) is correct because

SiCl_4

and

GeF_4

can act as Lewis acids due to the presence of vacant d-orbitals on Si and Ge, allowing them to accept electron pairs.
