Question # 1

The vapour pressure of a liquid depends upon

Choose an answer

amount of the liquid

surface area

temperature

size of container

Polarizability is responsible for intermolecular forces and it

Choose an answer

increases down the group

decreases down the group

almost remains the same

increased along a period

Dipole-induced dipole forces are also called

Choose an answer

dipole-dipole forces

ion-dipole forces

Debye forces

London-dispersion forces

The boiling point of higher alkanes are greater than those of lower alkanes due to reason that

Choose an answer

higher alkanes have greater number of atoms

the polarizabilities of higher alkanes are greater

higher alkanes have greater hydrogen bonding

higher alkanes have zig-zag structures

The nature of the attractive force in acetone and chloroform are

Choose an answer

dipole-induced dipole forces

dipole-dipole forces

ion-dipole forces

instantaneous forces

Amount of heat absorbed when one mole of a solid melts into liquid form at its melting point is called:

Choose an answer

heat of vaporization

latent heat of fusion

molar heat of fusion

molar heat of sublimation

The boiling points of the halogens

Choose an answer

increases down the group

decreases down the group

remains constant

can not be predicted

The long chains of amino acids are coiled around one another into a spiral by

Choose an answer

ionic bond

Van der Waal's forces

hydrogen bonding

overlapping of orbitals

At freezing point of water, the density decreases due to

Choose an answer

change of bond angles

change of bond lengths

cubic structure of ice

empty spaces present in the structure of ice

The polarizabilities of elements mostly increase down the group due to the reason that

Choose an answer

the atomic numbers increase

number of protons increase

number of shells increase along with increase of shielding effect

the behaviour of the elements remain the same

The B.P of glycerine at 760 torr pressure is

Choose an answer

200°C

290C°

250C°

262C°

H-bonding is maximum in:

Choose an answer

ethanol

benzene

diethyl ether

water

The boiling point of glycerin at 1 atmospheric pressure is:

Choose an answer

290°C

390°C

190C°

210°C

The B.P. of compound is mostly raised by

Choose an answer

dipole-induced dipole interactions

london dispersion forces

intramolecular H-bonding

intermolecular H-bonding

Strong dipole-dipole forces among the liquid molecules are responsible for

Choose an answer

very high heat of vaporization

very low heat of vaporization

cannot be predicted

negligible forces are these

The boiling point of H2O is 100°C while that of C2H5-OH is 78.5C°. The reason is that:

Choose an answer

H2O molecules are small-sized

the bond angles at oxygen atom are different

C2H5-group is electron donating

the number of H-bonds are greater in H20, than C2H5-OH

lce occupies more space than liquid water
