Answer:

Tetrahedral Parent and Geometry => #AX_4E_0#

Explanation:

From the formula given #HC Cl_3# there are 4 bonded pairs of electrons attached to the central element carbon (C) and zero (0) non-bonded pairs of electrons.

Non-bonded pairs = #("Valence" "Electrons" - "Substrate" "Electrons")/2#

Valence electrons = 1H + 1C +3Cl = 1(1) + 1(4) + 3(7) = 26

Substrate electrons = 1H + 3Cl = 1(2) + 3(8) = 26

Non-bonded #e^(-)# pairs = #(V_e - S_e)/2# = #(26 - 26)/2# = 0

Bonded #e^-# Pairs = number of substates attached to the central element = 4

#:.# Parent and Structural Geometry = #AX_4E_0# => Tetrahedral Geometry
