The tendency of $BF_3, BCl_3$ and $BBr_3$ to behave as Lewis acid decreases in the sequence

$\ce{ BF3 > BCl3 > BBr3 }$

$\ce{ BCl3 > BF3 > BBr3}$

$\ce{BBr3 > BCl3 > BF3 }$

$\ce{BBr3 > BF3 > BCl3 }$

Answer

$\ce{BBr3 > BCl3 > BF3 }$

Explanation

$p \pi$ back bonding decreases in the order ${BBr_3 > BCl_3 > BF_3}$
