Concept explainers
(a)
Interpretation:
Hybridisation of single-bonded nitrogen atoms has to be given.
(b)
Interpretation:
Hybridisation of double-bonded sulphur atoms has to be given.
(c)
Interpretation:
Hybridisation of double-bonded nitrogen atoms has to be given.
(d)
Interpretation:
Number of sigma bonds and number of pi bonds in the molecule have to be given.
Concept Introduction:
Sigma (σ) bonds are the bonds in which shared hybrid orbital’s electron density are concentrated along the internuclear axis.
Pi (π) bonds are the bonds in which shared un-hybridized orbital’s (p, d, etc) electron density are concentrated in above and below of the plane of the molecule.
(e)
Interpretation:
The position of sigma and pi bonds in the molecule has to be shown.
(f)
Interpretation:
Lewis structure for another resonance hybrid structure has to be shown.

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