Which bases are also called as hydrocarbon bases?

Oily or oleaginous bases include hydrocarbons derived from petroleum, which are called hydrocarbon bases. These bases are anhydrous and insol-uble in water. These bases are used for their emollient effect (to hydrate the skin) and as an occlusive dressing. They cannot absorb or contain water.

What are absorption bases?

An absorption base is an oleaginous composition containing an emulsifier or emulsifiers such that the composition is capable of absorbing water to form an emulsion of the water-in-oil type. It may be used as all or a part of the oleaginous material of an emulsion suitable for cosmetics, ointments, etc.

How do you find the coordination number?

Calculating the Coordination Number

  1. Identify the central atom in the chemical formula. Usually, this is a transition metal.
  2. Locate the atom, molecule, or ion nearest the central metal atom.
  3. Add the number of atoms of the nearest atom/molecule/ions.
  4. Find the total number of nearest atoms.


What is IUPAC name example?

The IUPAC name is therefore: 2,5,5-trimethyl-2-hexene. In example (2) the longest chain incorporating both carbon atoms of the double bond has a length of five. There is a seven-carbon chain, but it contains only one of the double bond carbon atoms. Consequently, the root name of this compound will be pentene.


What are hydrocarbons what are its types?

As the name suggests, hydrocarbons are made up of just two elements: hydrogen and carbon. In general, the carbon atoms are surrounded by hydrogen atoms to create the molecule structure. There are four main different types of hydrocarbons, which are classified as alkanes, alkenes, alkynes and aromatic hydrocarbons.


Which formula represents unsaturated hydrocarbons?

(2) CH2=CH2. - Unsaturated hydrocarbon means the hydrocarbon which contains atleast one double or triple bond between two carbon atoms.


What is the mole of glucose?

i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.


Why are saturated hydrocarbons less reactive?

Less reactivity of saturated hydrocarbons are due to presence of single bonds between carbon atoms. Paraffins (alkanes) may have straight chain or branched chain isomers which have different parent names.


What are aldehydes in chemistry?

aldehyde, any of a class of organic compounds in which a carbon atom shares a double bond with an oxygen atom, a single bond with a hydrogen atom, and a single bond with another atom or group of atoms (designated R in general chemical formulas and structure diagrams).


Is glucose an isomer?

Glucose, galactose, and fructose are monosaccharide isomers, which means they all have the same chemical formula but differ structurally and chemically.


What are the chemical properties of methane?

Methane has the chemical formula of CH4 and a molecular weight of 16.043 g/mol. The methane molecule is tetrahedral, with the carbon atom at the center and the four hydrogen atoms on the corners of the tetrahedron. Each C-H bond is equivalent, and each bond is separated by an angle of 109.5°.


Which compounds are called alkanes?

(i) Alkanes are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms. The general formula is written as where n = 1, 2, 3, 4 (ii) Alkenes are defined as the hydrocarbons in which a double bond is present between carbon and carbon atoms.


Is a penny an element a heterogeneous mixture a compound or a homogeneous mixture?

The copper coating on most pennies is an element, too. In graphite, all atoms are carbon atoms. In copper, all atoms are copper atoms. The metal under the copper coating of a penny is another element, zinc.


Why is isomer important?

Isomers. Isomers are compounds with identical chemical formulae, but different structures. They are very important in air pollution chemistry, because even slightly different structures can evoke dramatic differences in chemical and physical properties.


What kind of math is used in science?

In science, algebraic balance is required in chemical formulas, growth ratios, and genetic matrices. In science, math is used to analyze nature, discover its secrets and explain its existence and this is the big problem. Science is so complex and getting more so each day.


What is difference between chemical and physical?

Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes: Chemical changes cause a substance to change into an entirely substance with a new chemical formula.
