Question 1

what is an alkene

Answer 1

hydrocarbon containing a carbon-carbon double bond

Question 2

when naming a hydrocarbon, choose the longest continuous chain containing

Answer 2

both carbons in the double bond

Question 3

when numbering the carbons in a chain, number it so that the double bond carbons have the ___________ possible numbers.

Answer 3

LOWEST

Question 4

when naming and writing substituents in alphabetical order di, tri… are not included but ____, _____, _____ are.

Answer 4

sec, iso, tert

Question 5

why is this considered unsaturated

Answer 5

it does not have the maximum number of hydrogens

Question 6

why is this considered saturated

Answer 6

because it as the maximum number of hydrogens per carbon

Question 7

what rule says the more substituents something has, the more stable it is

Answer 7

Zaitsevs rule

Question 8

which one of these is the most stable and why

Answer 8

the second is the most stable because it has the most substituents

Question 9

which of these is the most stable alkene and why

Answer 9

the first because the longer the carbon chain attached the more stable

Question 10

what are the three steps to a mechanism

Answer 10

1. the electronegative atom takes electron and runs
2. the other atom says “crap i lost my electron! I need to go to an electron rich environment to get some (lone pair, double/triple bond)
3. when breaking a double bond the guy that said crap goes to the lower degree and the positive charge forms on the higher degree carbon

Question 11

what is the eyeball method side of the equation for IHD

Answer 11

IHD = of rings + # of pi/extra bonds

Question 12

what is the normal equation for IHD

Answer 12

IHD = # of carbons - (#H + #X)/2 + (#N/2) +1
