Concept explainers
Interpretation:
The type of bond between each pair of given atoms is to be identified.
Concept introduction: Electronegativity of an atom is its tendency to attract the shared pair of electrons in a bond towards itself. As we go down the group, electronegativity decreases as the size of atom increases. As we go across the period, electronegativity increases as the size of atom decreases.
The ionic bond is a bond formed by complete transfer of electrons from one atom to the other.
Covalent bond is a bond formed by sharing of electrons between the atoms. Polar covalent bond is a covalent bond in which the bonding electrons are shifted towards more electronegative atom in the bond.
To determine: The type of bond between each pair of given atoms.

- 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
