Concept explainers
(a)
Interpretation:
TInterpretation: The shape of the indicated N and O atom in the molecule needs to be determined.
Concept Introduction:
The geometry around any atom depends on the number of bond pairs and lone pairs of electrons around it. There are approximate bond angles between atoms, defined for a particular geometry as follows:
Molecular geometry around interested atom | Bond angle (') |
Linear | 180 |
Trigonal planer | 120 |
Tetrahedral | 109.5 |
Trigonal pyramidal | 109.5 |
Bent | 109.5 |
(b)
Interpretation:
The shape of the indicated 2 C atoms in the molecule needs to be determined.
