Alkenes

Question 1

Are alkenes unsaturated or saturated?

Answer 1

UNsaturated C=C

Question 2

why are alkenes reactive

Answer 2

as they
have 2 pairs of electrons in the c=c bond
C=C has a high electron density

Question 3

General formula of a cycloalKENE

Answer 3

CnH2n-2 eg C5H8=cyclopentene

Question 4

what is the purpose of electrophillic addition

Answer 4

to get RID of a double C=C bond

Question 5

what is an electrophile and what does it do

Answer 5

ELECTRON PAIR ACCEPTOR
short on electrons so are attracted to where there is lots of them

They r normally positvely charged ions H+
NO2+
delta positive charges are attratced to electrons

Question 6

what is the alkene bromine water test

and what is the colour change

Answer 6

shake alkene with bromine water in a test tube

goes from orange to colourless

Question 7

how are alkyl hydrogen sulfates produced

and what can this product then reactive with to form alochol

Answer 7

alkene+ cold sulfuric acid

cold water

Question 8

major carbocations are more stable carbocations because??

Answer 8

Tey have more R groups

tertiary carbocation is the most stable type
