Question

describe the hybridization state of aluminum in aluminum trifluoride (alf₃). select the single best answer. sp sp² sp³ sp³d sp³d²

Explanation:

Aluminum in $AlF_3$ has 3 bonding - pairs and 0 lone - pairs. The steric number (SN) is calculated as the sum of bonding - pairs and lone - pairs. Here, $SN=3 + 0=3$. According to the hybridization rules, when the steric number is 3, the hybridization is $sp^{2}$.

Answer:

$sp^{2}$
