Question 1

carbocation🌷

Answer 1

trivalent carbon
+ charge
unstable
sp2 hybridised
120*
observed in H + C nmr spec
reactive intermediate

Question 2

how are carbocations stabilised🌷

Answer 2

they crave electron density
groups around them can donate some electron density
to it’s empty P orbital
to help stabilise it

Question 3

hyperconjugation🌷

Answer 3

sigma bonds from CH
donate electron density
more CH bonds = more stable

Question 4

order of stability of carbocations

Answer 4

tertiary
secondary
primary
just Hs around it

Question 5

carbocations can also be stabilised using

Answer 5

conjugation
move the + charge to the end of the molecule??

Question 6

🌷greater degree of resonance means

Answer 6

greater stability
more number of resonance structures
more stable the molecule becomes
due to less electron electron repulsion

Question 7

carbocations can also be stabilised by🌷

Answer 7

lone pairs donating electron density
these groups that donated then would then get a + charge.

Question 9

more substituted alkenes form what type of carbanion🌷

Answer 9

a less stable anion

less acidic

Question 10

as degree of unsaturation increases why does stability increase and acidity increase🌷

Answer 10

higher degree of unsaturation = hybridisation
sp3 vs sp

sp has more s character and therefore is more stable : closer to nuc and therefore more stable : more acidic

Question 11

is an anion is more stable,, what does that mean about the h🌷

Answer 11

it’s more acidic

Question 12

what form of stability makes a hydrogen more acidic due to making it more stable🌷

Answer 12

more acidic = more stable

more acidic and stable bc it’s aromatic: flat, huckels rule, conjugated, cyclic

Question 13

more conjugation of the anion means🌷

Answer 13

more stable
more acidic

Question 14

more electronegative atom near an anion means the anion is🌷

Answer 14

more stable
less e- near it
more acidic
