Question 1

What is the general formula for alkanes

Answer 1

Cn H2n + 2

Question 2

What does IUPAC stand for

Answer 2

international union of pure and applied chemistry

Question 3

why is carbon a base molecule in structures

Answer 3

4 covalent bonds
create long carbon chains
branches
rings
unlimited possibilities

Question 4

what is an alkane

Answer 4

Hydrocarbon with single bonds

Question 5

what is a hydrocarbon

Answer 5

hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.

Question 6

rules for naming in general

Answer 6

alphabetical order
keep the bond number low
root must be as long as possible

Question 7

define isomerism/ what an isomer is

Answer 7

a compound with the same molecular formula as another compound but different structure

Question 8

what is an condensed structure for example

Answer 8

CH2(CH3)CH3

Question 9

what does saturated mean and how does that affect alkenes and alkynes

Answer 9

alkenes and alkynes are not saturated as they do not have the most H’s as possible due to their double/triple bonds unlike Alkanes

Question 10

what are aromatic Hydrocarbons

are they saturated?
are they stable and why?
do they smell?
what are they an example of

Answer 10

they are not saturated
they are stable due to resonance structure(double bonds can move in benzene for ex)
they do smell

benzene

Question 11

when benzene is a branch what do you call it?

Answer 11

phenyl

Question 12

what type of configuration is CIS/TRANS

Answer 12

it is a type of CONFIGURATIONAL (break bonds to convert one to another)

Question 13

why are cyclic cis/trans

Answer 13

because their is an definite set orientation in space creating inflexibility

Question 14

reminder that when looking at bow tye shape that the root is the longer part not just the middle . it is the carbons on the sides of one side through the middle to other side

Answer 14

ye

Question 15

know that skeletal can be cis/trans

Answer 15

ye

Question 16

What is an geometric isomer vs structural isomer

Answer 16

Structural isomers only have the same molecular formula with another but different shape, furthermore they are also flexible and can rotate

Geometric isomers can not rotate as they do not have a flexible shape as they have a set orientation in space creating inflexibility. They also contain cis/trans prefix depending on where their 2 groups are located.

cis groups tend to be more polar making them bond well and be more reactive while trans make the atom less reactive.
