Nylon polyesters are the polymers, so they are macromolecules made up of a high number of the monomers. These monomers are covalently bonded to give rise to the nylon polyesters. Their properties are greatly dependent on the arrangement and the type of monomers in the polymer molecules. There is a minute difference between the nylon, … Read more
Amines are the derivatives of the ammonia compound. These derivatives are formed by the replacement of the hydrogen atom of ammonia by the alkyl or the aryl groups. The amines thus produced are classified into different amines. The amines are basically classified as primary, secondary and tertiary amines depending upon the number of the alkyl … Read more
Polythene is also known as polyethylene, and generally it is abbreviated as PE, is the most commonly used plastic in this era. It has low strength, hardness, and rigidity but it has high impact strength, high ductility, and low friction. Under the persistent force, it shows the strong creep that can be possibly reduced by … Read more
A larger portion of the commercial polymers is constituted by the copolymers and is known as copolymerization. They vary in the distribution of the polymers and the composition. The monomers can have similar different physical properties and cause a variety of copolymers with different uses and properties. For example, small amounts of trifunctional monomers, or … Read more
The Amines are compounds that are derived from Ammonia group. The ammonia group has one nitrogen atom bonded with four hydrogen atoms respectively. The Amines are derived from the Ammonia by replacing one or more than one hydrogen atom connected to nitrogen. The group bonded is either an Alkyl group or any Aryl group respectively. … Read more
Amines are basically the derivatives of the Ammonia (NH3). These derivatives are formed by the replacing of the hydrogen groups from the Ammonia. The replacing of hydrogen atom in the ammonia is done by either the Alkyl groups or the Aryl groups respectively. The Amines as such behave like base in nature. This is because … Read more
p-Block Elements: Group 17 Oxoacids of halogen The fluorine atom is highly electronegative and compact in size. Therefore, it can only form a single oxoacid. HOF is fluoric(I) acid or hypofluorous acid. Alternatively, the other elements of the halogen family produce several oxoacids with multiple oxygen atoms. The focal halogen molecule in these oxoacids is … Read more
p-Block Elements: Group 17 Interhalogen compounds Interhalogen compounds are produced by reacting halogens with each other. Most interhalogen compounds resemble the properties and behaviours that are intermediates of those of the two-parent halogens. Inter-halogens can be grouped into four categories: XY, XY3, XY5, and XY7. Here X halogen atom is more electropositive and larger in … Read more
p-Block Elements: Group 17 Compounds of halogen Hydrogen halides are made up of binary compounds of halogens and hydrogen. They form strong hydrohalic acids in water, except HF. The hydrogen-fluorine bond is highly polar because fluorine is much more electronegative than hydrogen, and each fluorine atom in HF has three lone pairs of electrons. The … Read more
p-Block Elements: Group 17 Trends in physical and chemical properties All Group 17 elements are non-metals. Hence, they are insulators of heat and electricity. The density of halogens increases down the group. Halogens have low melting and boiling points which increase down the group. The forces of attraction between the molecules go weaker as the … Read more
