Organic Chemistry Questions and Short Answers
What is known as the Most Probable kinetic energy? (Collision Theory Chemistry)
Most probable kinetic energy is the energy possessed by the maximum number of reactant molecules at a temperature T, and it is shown as a peak on the Maxwell-Boltzmann energy distribution graph (fraction of molecules versus Kinetic energy).
Chloroacetic acid is a stronger acid than acetic acid. Give Reason.
The replacement of the hydrogen in acetic acid (H-CH2-COOH) with the chloro gives chloroacetic acid (Cl-CH2-COOH). Therefore, Acetic acid and Chloroacetic acid have carboxylic acid (R-COOH) as the principal functional group.
What factors affect the strength of polar-nonpolar molecular interactions?
The strength of polar-nonpolar interactions is affected by the atomic size of the nonpolar atom (or molecule) and the electronegativity of the polar molecule.
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 is a Bond length ?
An easy way to identify organic compounds is to look for several atoms in a long chain. These long chains are covalent bonds. So, the length of the bond and the factors affecting it becomes very important.
Such a bond formation occurs only when the atoms that want to form covalent bonds have the right concentration, orientation, and speed.
Identify the monochlorination product of isomeric alkane C5H12
Among the isomeric alkanes of molecular formula C5H12, identify the one that on photochemical chlorination yields
i) A single monochloride
ii) Three isomeric monochlorides
iii) Four isomeric monochlorides.

What are valence and core electrons? How to determine a valence electron?
Learning Objective: To study about the electrons and judge its reactivity based on its placement around an atom’s orbital. We will also determine how to find the outermost shell electrons from its group number and electronic configurations.

What factors affect the metallic bond strength?
A metal atom is large, so the nucleus cannot attract and hold its outermost electrons. The metal loses those electrons and becomes positively charged kernels. The electrons then flow in the solid structure passing between these positive kernels.
