part 2

Question 1

how did Fritz London describe London forces

Answer 1

according to him, non polar did not have charge, not dipole dont have IMFOA, So he said that they cant exist as liquid or solid but only gas

Question 2

which molecules have FOA but are non polar molecules

Answer 2

Benzene (C6H6) and Carbon tetrachloride (CCl4) are in liquid state but are non polar

Question 3

when does a non polar molecule have FOA

Answer 3

The FOA is called Londons foa. Its when an atom’s electron does a rotation and somehow its position change so it shows a FOA

Question 4

concept of hydrogen bonding

Answer 4

the bond formed by hydrogen and the electronegative element - Fluorine, oxygen and nitrogen

Question 5

state variables of gas

Answer 5

To describe the physical condition of gas we require gas variables
4 state variables: temperature, pressure, volume and no. of moles

Question 6

state variable: volume

Answer 6

the volume of gas is the volume of container

units: L, ml, cm3, dm3, m3

Question 7

state variable: temperature

Answer 7

it is the measure of heat content of gas system

units: Kelvin(K), Celcius, and Fahrenheit

Question 8

state variable: pressure

Answer 8

the force applied per unit area

units: bar, atm, torr, mm/cm of Hg, Pa
