(a)
Interpretation:
The Lewis dot structure for TeCl2 must be drawn.
Concept Introduction :
Lewis dot structure is the representation of a molecule using valence electrons shown as dots.
Te is a p block element of group 16 with 6 valence electrons.
(a)
Answer to Problem 5E
Lewis dot structure for TeCl2 is given below.
.
Explanation of Solution
In TeCl2, Te is the central atom which is bonded to two Cl atoms. There are three lone pairs of electrons on each Cl atom and two lone pair of electrons on Te atom.

- Show the mechanism steps to obtain the lowerenergy intermediate: *see imagearrow_forwardSoap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups.
