Question

Among the halides (1)BCl3 (2) AlCl3 (3) GaCl3 (4) InCl3 The order of decreasing Lewis acid character is: (A) 1,2, 3,4 (B) 2, 3,4,1 (C) 3,4, 2, 1 (D) 4, 3, 2, 1

Tardigrade Admin · Accepted Answer

The acidic character of chlorides increases down the group BCl3 is weak acid to show pπ - pπ back bonding.

Q. Among the halides
$(1) BC l_{3}$
$(2) A lC l_{3}$
$(3) G a C l_{3}$
$(4) I n C l_{3}$
The order of decreasing Lewis acid character is:

$1, 2, 3, 4$

$2, 3, 4, 1$

$3, 4, 2, 1$

$4, 3, 2, 1$

The acidic character of chlorides increases down the group $BC l_{3}$ is weak acid to show $p π - p π$ back bonding.
