Question 1

what is geometric isomerism

Answer 1

the same molecular formula, but a different spatial arrangement of atoms around a double bond

Question 2

what is a positional isomerism

Answer 2

Same molecular formula functional group in different position

Question 3

Redox reactions

Answer 3

a reaction in which electrons are transferred from one species to another

Question 4

Nucleophile

Answer 4

species can donate a lone pair of electrons to form a covalent bond

Question 5

substituition

Answer 5

replacement of one atom or group of atoms by another

Question 6

free radical

Answer 6

species with unpaired electrons

Question 7

addition

Answer 7

combination of two or more molecules to form a single molecule

Question 8

oxidising agent

Answer 8

electron acceptor

Question 9

Dynamic equilibrium

Answer 9

a reaction in which the forward and reverse reaction are proceeding at the same time, therefore concentration stays constant

Question 10

Collision theory

Answer 10

number of collisions between particles per second

Question 11

fingerprint region

Answer 11

the part of the infra red spectrum characteristic go an unknown molecule

Question 12

addition polymerism

Answer 12

combination of a large number of monomers to form a single chain, without wage being a product

Question 13

homolytic fission

Answer 13

breaking covalent bonds in such a way the one electron goes to each atom

Question 14

heterolytic fission

Answer 14

breaking covalent bonds in such a way that both electrons go to one atom

Question 15

equations that show how Cl free radicals damages the ozone layer

Answer 15

Cl- + O3 –> ClO- +O2

ClO- + O3–> 2O2 + Cl-

Question 16

If there was a fire with a group 2 metal, why wouldn’t you add water to it

Answer 16

Mg + H2O –> Mg(OH)2 + H2

H2 is highly flammable and the reaction is exothermic so a lot of heat energy would be created, aiding the fire

Question 17

three types of alcholos

Answer 17

Primary, secondary and tertiary

Question 18

three properties the hydroxyl group gives the alcohol

Answer 18

> High melting point
they are highly reactive
they are soluble

Question 19

what is used to oxidise alcohols

Answer 19

acidified potassium dichromate

Question 20

what colour does an alcohol go if it is oxidised

Answer 20

orange to green

Question 21

what is used as a catalyst in hydration of ethane

Answer 21

conc h2so4

Question 22

what is use in the hydration of an alcohol

Answer 22

con H2so4

Question 23

what type of reaction is an elimination reaction

Answer 23

elimination

Question 24

mechanisms

Answer 24

nucleophilic substitution
electrophilic addition
free radical substitution
Elimination

Question 25

primary alcohol is oxidised to…

Answer 25

aldehyde, then under reflux carboxylic acid

Question 26

how to text for a carboxylic acid

Answer 26

add carbonate and there should be immediate fizzing and CO2 produced

Question 27

Formula of ethanol

Answer 27

C2H5OH
