DF8 + DF9

Question 1

units in ideal gas equation

Answer 1

P = pressure in PASCALS
V = volume in METRES CUBED
n = moles
R = gas constant JOULES PER KELVIN PER MOLE
T = temperature in KELVIN

Question 2

isomers

Answer 2

molecules with the same molecular formula, but differ in the way in which their atoms are arranged

Question 3

structural isomers

Answer 3

same molecular formula, different structural formulas

eg. chain isomerism, functional group isomerism, position isomerism

Question 4

stereoisomers

Answer 4

same molecular formular and atoms in same order, but atoms have different arrangement in space
eg. E/Z, optical isomerism

Question 5

chain isomerism

Answer 5

with 4+ carbons in a chain there are different arrangements possible (butane and methylpropane)

Question 6

position isomerism

Answer 6

molecules differ in location of functional group on the molecule

Question 7

functional group isomerism

Answer 7

same molecular formula but arrangement of atoms results in different functional groups

Question 8

E/Z isomerism

Answer 8

same molecular formular but atoms arranged differently in space
E - identical groups on opposite sides (one top one bottom)
Z - identical groups on same side (both top/both bottom)
