(a)
Interpretation: If there are two bonding pairs and two non-bonding pairs of electrons of a central atom in a molecule, its shape needs to be predicted.
Concept Introduction: VSEPR theory is used to predict the molecular shape with the help of electron pairs around the central atoms of the molecule. It is based on the assumption that the shape of the molecule is such that there is minimum electronic repulsion between the valence shell and the atom.
(a)
Explanation of Solution
The total number of pairs of electrons will be the sum of bonding and non-bonding pair of electrons. Thus, it will be 4 for the given molecule. For 4 electrons, the hybridization will be
(b)
Interpretation: If there are four bonding pairs and zero non-bonding pairs of electrons of a central atom in the molecule, its shape needs to be predicted.

- Soap 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. Draw the above carboxylic acidcarbon chain but as the two variants of detergents. *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forwardWhat are the reactions or reagents used? *see imagearrow_forward
