alkenes

Question 1

alkenes are?

Answer 1

hydrocarbons with a double carbon carbon bond that is always saturated

Question 2

what does the carbon carbon double bond have?

Answer 2

high electron density so its easy to be attracted by electrophiles

Question 3

what is the pi bond?

Answer 3

a pi bond has sideways overlap and is above and below the bonding atoms
a pi bond is also weaker then a sigma bond

Question 4

what is the sigma bond?

Answer 4

the sigma bond has direct overlap of orbitals and is between bonding atoms

Question 5

what molecular shape does alkenes have

Answer 5

trignal planer at 120 degrees

Question 6

what is steroisomerism

Answer 6

compounds with the same structural formula but different arrangement of atoms in space

Question 7

what is a z-isomer?

Answer 7

it is substitutes that are on the same side
VAS HAPPEING

Question 8

what is a e-isomer?

Answer 8

either side of the substrate

Question 9

in order to get e/z isomerism you need?

Answer 9

double bond (restricted rotation)
the C atoms in the C=C need two different groups ( different C.I.P priorities )

Question 10

what is cis isomers?

Answer 10

same side
only applies to E if there is a H on each carbon atom

Question 11

what is trans isomers

Answer 11

different sides (z)
