Bonding in Molecular Solids
Dipole-dipole interactions These types of forces occur in molecular solids which have polar molecules. A polar molecule has separate centres of positive and negative charges. These forces arise due to electrostatic attraction of the other molecule and vice..
ii) Boiling points
They are relatively less polar in comparison with isomeric cyanides. Consequently, their melting and boiling points are relatively low in comparison with cyanides of same molecular mas..
2. Boiling points
Aldehydes and Ketones have relatively high boiling point as compared to hydrocarbons of comparable molecular masses. This is because the aldehydes and ketones contain polar carbonyl group and therefore have stronger intermolecular dipole dipole interactions between the opposite..
Physical Properties
Being polar in nature, the acid derivatives have higher boiling points than hydrocarbons of comparable molecular masses. Acid chlorides, anhydrides and esters have nearly the same boiling points as the aldehydes and ketones of comparable molecular masses. Their b..
iii) Solubility
The cyanides with low molecular mass are soluble in water. This is due to the tendency of their molecules to form hydrogen bonds with water molecules...

Physical Properties of Alcohols and Phenols - Alcohols and Phenols consist of two parts, an alkyl/aryl group and a hydroxyl group. The properties of alcohols and phenols are due to the -OH group. The alkyl and aryl groups modify these properties. 1. The lower members of alcohols are colourless, vol..
Boiling point
The boiling points of alkenes gradually increase with an increase in the molecular mass (or chain length). This indicates that inter-molecular attractions become stronger with an increase in the size of the molecule. Branched chain alkenes have lower boiling points than the cor..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
'I spent like 10 mintues writing a chart needed for the problem but the tutor was very much helpful.. Thank you Tutor Vista'
It was fun! It showed me a easier way to do multiplication with bigger numbers,Thank you all - Christian
Great tutor! Really takes the time to make sure you understand how to work each equation
