alkenes

what are alkenes

alkanes with a double bond involved

whats the naming prosses of alkenes

the same as alkanes but the 1 carbon is at the double bond and the suffix is ene

what are constitutional isomers of alkenes

they differ in connectivity

what are geometric isomers

the connectivity in the atoms is the same but they have diffrent spcaial arragments

what is the double bond that an alkene have made from

a sigma bond or a pi bond

whats a sigma bond

overlap of 2 s orbitals

whats a pi bond

sidways overlap of 2 ajacent p orbitals

what bonds cant roatate in alkenes

double bonds

why cant double bonds rotate

due to the way the pi bonds overlap

beacuase the double bpnds cant roates what does i cause the alkenes to form

steryoisomers

what are steryoisomers

they ahve the same structural form but diffrent arrangement in space - when they have 2 diffrent groups attached to them

what ate the 2 diffrent isomers

E and Z

what is the Z isomer

it has the same groups either both above or both below

what is another name for Z isomers

cis

what is the E stereoisomer

has the same groups but across the fouble dond

whats another name for E isomers

trans

in terms of reacitivity what does the pi bond cause

high electron density above and below the plane of the molecue

what the pi bonds polar or non polar

non polar

what are the pi bonds likly to be attacked by

ellectriphilic addiction reaction

what is an electrophillic addition reaction

the double bond gets opend up and atoms are added to the carbon

what do electrophiles incluse

positivyl charged ions and polar molecules sice the positive atom is attracted to places with lots of electrons

what does markivnikovs rule do

predicts the elcertonegitivity of electrophillic addtions
