Burning wood because heat indicates a chemical change
The electron-group arrangement of CO₃²⁻ is trigonal planar. The molecular shape is trigonal planar, and the ideal bond angle(s) is CO₃²⁻ is 120°
<h3>What is the molecular geometry of a compound?</h3>
The position of the compound's electrons and nuclei can be seen in the molecular geometry. It demonstrates how the form of the complex is created by the interaction of electrons and nuclei.
Here, according to the VSEPR theory, the shape of the carbonate ion is trigonal planar. The carbon will be in the center.
Thus, the electron-group arrangement and the shape of the carbonate ion are trigonal planar. The bond angle will be 120°.

Answer:
doublet
Explanation:
Proton MNR is used for the determination of no. of equivalents protons in a molecule
In the molecule, single NMR signal is produced for each set of protons.
Signal splitting is called spin-spin coupling and the splitting of signals depends upon the no. of neighboring proton.
The no. of signal for a proton is equal to n+1, where n is neighboring protons.
In 1-bromo-2-methylpropane, neighboring proton for both methyl protons are one. But the chemical environment of both the methyl protons are different.
Neighboring proton for methyl protons = 1
No. of signal for methyl protons = 1+1 =2
Hence, two doublets will be generated for each set of methyl protons. protons.
Remember the relationship
- P is indirectly proportional to V
So
The pairs are
- (2,4)
- (1,8)
- (4,2)
- (12,2/3)
- (2/3,12)
And so on
