There are zero number of methylene groups in the substance 2,4-dimethylhexane. Methylene groups are the part of a molecule that contains a carbon atom that has a double bond or =CH. Looking at the structure of 2,4-dimethylhexane, you cannot see any carbon atom that has a double bond.
The non-contact forces portfolio includes Gravitational force, Magnetic force and Electrostatic force.
<h3>What is non contact force?</h3>
Non contact forces are those forces which are applied on any object without any physical interference or contact.
Some non-contact forces are:
- Gravitational force: It acts between two objects and depends on the masses of the object and distance between that objects.
- Magnetic force: It acts due to the motion of the charged particles.
- Electrostatic force: It is a type of induced force which is generated due to rubbing of two objects but when it is generated it remains even after removing the contact of previous objects.
Hence Gravitational force, Magnetic force and Electrostatic force are the non-contact forces.
