Organic Chemistry Questions and Short Answers

Dipole-dipole interactions occur in polar molecules where the difference in electronegativity between the combining atoms creates positive and negative dipoles. These opposite poles align and result in electrostatic attraction throughout the polar medium. So, naturally, the strength of the interaction would depend on the magnitude of the charges and their distance, explained by the Coulombic law. So, the higher the magnitude of the charges and the lesser the distance between them, the stronger the dipole-dipole attractive interaction.

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.

Around the early 1800s, scientists began to notice the presence of isomerism in all types of compounds; however, at the time, it was referred to using different names.

The term allotrope was used to describe different varieties of an element that existed in different physical forms, such as diamond or graphite for carbon or monoclinic or rhombic for sulfur. Polymorphism was used to explain compounds that occurred in more than one crystalline form, like aragonite and calcite, both crystalline forms of calcium carbonate.

The discovery of isomerism marked the advent of structural chemistry, where it became significantly important to establish structural formulas, welcome the abundance of structurally diverse compounds, classify them, and study their individual properties and impacts.

The Inductive effect is the outcome of Electronegativity; therefore, they are different and not the same.
