Solution

space Electronic space Configuration space of space 13 left parenthesis Al right parenthesis space equals space 1 straight s squared 2 straight s squared 2 straight p to the power of 6 space 3 straight s squared space straight P subscript straight x superscript 1

₁₃Al (Excited state) = ls²2s-²2p⁶3s¹3p_x¹3p_y¹ .Hence in AlCl₃, Al undergoes sp²hybridization to give it planar triangular structure. In AlCl₄ , the empty 3p. orbital is also involved so that hybridization is sp³ and its shape is tetrahedral.
