Molar Mass of An Element and Avogadro's Number

This page will describes molar mass of an element and avogadro's number. Atomic mass units provide a relative scale for the masses of the elements. But since atoms have such small masses, no usable scale can be devised to weigh them in calibrated units of atomic mass units. In any real situation, we...

Atomic Mass

This page describes about chemical structure and formulas in studying the mass relationships of atoms and molecules. These relationships in turn will help us to explain the composition of compounds and the ways in which composition changes. The mass of an atom depends on the number of electrons, protons,...

Chemical and Physical Properties of Matter

This page describes chemical and physical properties of matter. As we know, every matter has different properties. Substances are identified by their properties as well as by their composition. Color, melting point, and boiling point are physical properties. A physical property can be measured and...

sp Hybridization of Alkynes

The common hybridization in alkynes is sp. Alkynes are compound that have triple bond between it's carbons. Acetylene is linear, with a carbon–carbon bond distance of 120 pm and carbon–hydrogen bond distances of 106 pm. Linear geometries characterize the H-C≡C-C and C-C≡C-C...

Nomenclature of Alkynes

Alkynes can be named both in IUPAC and trivial methods. Here's the nomenclature of alkynes. The systematic name of an alkyne is obtained by replacing the “ane” ending of the alkane name with “yne.” Analogous to the way compounds with other functional groups are named, the longest...

Source of Alkynes

Alkynes are useful chemical. They're can be intermediate for other organic chemical's synthesis. They're so many sources of alkynes. Acetylene was first characterized by the French chemist P. E. M. Berthelot in 1862 and did not command much attention until its large-scale preparation...
