Which among the following intermolecular forces of attraction is the most commonly occurs in between non-polar molecules?
dipole-dipole interaction
hydrogen bonding
ionic bonding
Van der Waals forces
A solution that contains more amount of solute than the solvent results in what type of solution.
unsaturated
supersaturated
saturated
Adding more carbon to the chain makes the compound more non-polar which makes it soluble with water.
TRUE
FALSE
If the compound is soluble with water and has a pH of 7, it is classified as:
LMW basic
LMW neutral
HMW neutral
HMW strongly acidic
If the compound is insoluble with water but soluble in 5%HCl, 5%NaOH, and 5%NaHCO3, then it is:
low moleular weight amine
high molecular weight carboxylic acid
high molecular weight phenol
high molecular weight neutral
Which among the following intermolecular forces of attraction is the most commonly occurs in between polar molecules?
dispersion forces
Vander waals
dipole-dipole
ionic bond
In organic compounds, the boiling point increases as the number of carbon atom increases since more energy is required to break the ionic bonds between the molecule.
TRUE
FALSE
Branched isomer have lower boiling point than straight isomer because the molecules in branched isomer have more surface area than the straight chain.
true
false
The higher the intermolecular forces between the liquid particles, the harder it is for it to escape into vapor pressure which leads to a higher boiling point.
TRUE
FALSE
Presence of non-volatile impurities leads to high boiling point due to increase in the vapour pressure of the liquid
true
false
The tighter the molecules are packed, the higher the melting point.
If the structure of the molecules is loose, then the melting point would be lower.
1st statement is TRUE, 2nd statement is FALSE
1st statement is FALSE, 2nd statement is TRUE
Both statements are TRUE
Both statements are FALSE
Presence of impuries leads to an increase in the melting point range.
true
