What is a monofunctional compound?
[‚män·ō¦fəŋk·shən·əl ′käm‚pau̇nd] (organic chemistry) An organic compound whose chemical structure possesses a single highly reactive site.
What is functionality of a compound?
In chemistry, functionality is the presence of functional groups in a molecule. In organic chemistry (and other fields of chemistry) functionality of a molecule has a decisive influence on its reactivity. A monofunctional molecule possesses one function, a difunctional two, a trifunctional three, etc.
What is polyfunctional compound?
Organic compounds which contain two or more functional group are called polyfunctional compounds. If two groups of the same preference occupy identical positions from either end of the parent chain, the lower number must be given to the group whose prefix comes first in the alphabetical order.
What is difunctional chemistry?
Definition of ‘difunctional’ 1. (of a compound) having two sites in the molecule that are highly reactive. 2. a compound having two sites in the molecule that are highly reactive.
What is monofunctional example?
: of, relating to, or being a compound with one reactive site in a molecule (as in polymerization) formaldehyde is a monofunctional reagent.
What is a difunctional monomer?
Difunctional monomers are useful for imparting crosslinking or branching sites to polymer architectures. The “spacer” group between the acrylic end groups often helps determine the physical and mechanical attributes of the resulting crosslinked polymer structure. Long-chain hydrophilic, crosslinking monomer.
What are the two main groups polyfunctional compounds?
In a polyfunctional compound, one of the functional groups is selected as the principal functional group while all other functional groups are treated as substituents….Principal functional group.
| COMPOUND NAME | FORMULA |
|---|---|
| Acid chloride | -COCl |
| Acid amides | -CONH2 |
| Nitrile | -CN |
| Aldehyde | -CHO |
What compounds are called polyfunctional and Heterofunctional?
Polyfunctional compounds contain several identical functional groups, for example, chloroform and glycerol. Molecules with different functional groups are considered as heterofunctional compounds, they may be related to several classes. For example, lactic acid is both an alcohol and a carboxylic acid.
What does difunctional mean?
highly reactive
Definition of difunctional : of, relating to, or being a compound with two highly reactive sites in each molecule.
Which polymer is trifunctional?
When the structural unit is trifunctional (has three bonding sites), a nonlinear, or branched, polymer results. Ethylene, styrene, and ethylene glycol are examples of bifunctional monomers, while glycerin and divinyl benzene are both polyfunctional.
What are conducting polymers in chemistry?
Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. The biggest advantage of conductive polymers is their processability, mainly by dispersion.
