Answer is: Benzene is trigonal (or triangular) planar.
VSEPR theory (The Valence Shell Electron Pair Repulsion Theory) uses the AXE notation (m and n are integers, m + n = number of regions of electron density).
For benzene molecule (C₆H₆):
m = 3; the number of atoms bonded to the central atom.
n = 0; the number of lone pairs on the central atom.
C. Single-replacement
Chlorine replaces Bromine in KBr.
Answer:
Ketone
Explanation:
As you are stating here, we have a carbonated chain of three carbons, and the first and last has 3 Hydrogens, then this means that we have CH₃ . The center carbon is a carbon double bonded to oxygen.
In general terms this belongs to the carbonyl group. However, this alone does not represent a functional group, but when it's in a chain with other radycals or chains, it becomes a functional group.
In this case, the molecule you are talking here is the following:
CH₃ - CO - CH₃
This molecule is known as the Acetone, and has the general form of:
R - CO - R'
Which belongs to a ketone as a functional group.
Answer: intermolecular forces are described as forces that either cause attraction or repulsion between neighbouring particles or molecules
Explanation: liquids with strong intermolecular forces has the following properties:
1.) High boiling point
2.) high surface tension
3.) Low viscosity
4.) Low vapour pressure
While liquids with weak intermolecular forces has the following properties:
1.) Low boiling point
2.)low surface tension
3.) High viscosity
4.) High vapour pressure.
