Organic Chemistry

Structural Isomers

Structural isomers have the same molecular formula but differ in how the atoms are bonded to each other; that is, their attachment style is different.

Such molecules that differ by bonds while still having the same molecular formula are also known as constitutional isomers.

 

Collision Theory

Collision theory is applicable only to bimolecular reactions mostly gases where the reactant molecules are considered as hard spheres that must collide with sufficient threshold energy and must be correctly oriented for the collision to be effective that results in the product formation.

The rate of the reaction, therefore, depends on the collision frequency, threshold energy, and the orientation (steric/probability) factor.

Differentiating complete structural formulas and condensed structural formulas using examples

Draw complete structural formulas and  condensed structural formulas for

        a) three compounds of formula C3H8O

        b) five compounds of formula C3H6O

The condensed structural formula disguises the molecule's true vastness by revealing only the number of atoms present. What remains hidden from sight are the bond connections, the bond angles, and their three-dimensional arrangements, so what we observe is just the molecule's literal condensed form.

Identify the Organic Compound with Molecular Formula C8H16O2- Aldehydes, Ketones and Carboxylic Acids

An Organic Compound 'A' molecular formula C8H16O2 was hydrolyzed with dilute H2SO4 to give a carboxylic acid 'B' and an alcohol 'C.' Oxidation of 'C' with chromic acid also produced 'B.' On dehydration 'C' gives 1-but-ene. Write the equations for the reaction involved.

1) The first step is find out the Degree of Unsaturation (the number of double bonds or the presence of a ring) in the compound. 

The formula is, 

What are haloalkanes and haloarenes? How can they be classified?

A Haloalkane is the Halogen derivative of an alkane obtained by replacing of one or more hydrogen atoms.

For example, when one Hydrogen of an alkane, Methane, is replaced with a Halogen, for instance, Chlorine, the haloalkane obtained is chloromethane.

Electron

An electron is a negatively charged elementary particle that constitutes an atom, denoted as e- or β-. The electrons are present in the outer-nuclear region of an atom as clouds.

 

Carbocation

A carbocation is a positively charged, trivalent carbon ion that acts as a reactive intermediate in many organic reactions.

With three bonds and only six electrons, carbocations have an incomplete octet and, therefore, electron deficient. It functions as an electron acceptor and an electrophile forming new Carbon-Carbon (C-C) bonds.
