Alkane + Oxygen -> CarbonMonoxide + Water

Front (Question)

How are alkanes formed

Back (Answer)

Fractional Distillation of Crude Oil

Front (Question)

How are alkenes formed

Back (Answer)

By cracking (decomposing) alkanes.

Front (Question)

What is the general formula for addition of halogens to alkenes?

Back (Answer)

halogen + alkene -> dihaloalkene

Front (Question)

What is the general formula for the formation of alcohols?

Back (Answer)

alkene + water -> alcohol

#10

Front (Question)

What happens to the bonds in the alkene when it reacts with water to form an alcohol?

Back (Answer)

The C=C double bond breaks.

#11

Front (Question)

“ane” in alkane refers to?

Back (Answer)

Being saturated

#12

Front (Question)

“ene” in alkene refers to?

Back (Answer)

Having a C=C double bond

#13

Front (Question)

“ol” in alcohol refers to?

Back (Answer)

The presence of an OH

#14

Front (Question)

What is a renewable way to produce alcohol?

Back (Answer)

Fermentation of sugars More things to know: It is a batch process Has a purity of max 15% Sugars are decomposed by yeast, making alcohol and CO2

#15

Front (Question)

Carboxylic acids are made by?

Back (Answer)

Reacting an alcohol with an oxidising agent

#16

Front (Question)

Back (Answer)

weak COOH partially

#17

Front (Question)

What is a common oxidising agent that we can use for alcohols?

Back (Answer)

potassium dichromate (K2Cr2O7)

#18

Front (Question)

Reacting alcohols and carboxylic acids makes

Back (Answer)

esters

#19

Front (Question)

the “oic acid” in carboxylic acid names refers to?

Back (Answer)

The presence of a COOH with a C=O group. and C-O-H (on the same C)

#20

Front (Question)

How are polyesters formed?

Back (Answer)

by adding a diacid and diol

#21

Front (Question)

What is a byproduct of forming a polyester

Back (Answer)

(2n-1)H2O

#22

Front (Question)

How are esters named?

Back (Answer)

first part from alcohol second part from carboxylic acid Suffixes -yl and -oate i.e. ethanol + propanoic acid -> ethylpropanoate

#23

Front (Question)

How are polyalkenes formed and named

Back (Answer)

Many (1000s) of alkenes join poly + name of original alkene.

#24

Front (Question)

Which catalyst is needed for cracking?

Back (Answer)

Al2O3
