Front (Question)

What are the reaction conditions for reacting a halogenoalkane to form an alcohol?

Back (Answer)

• Use warm aqueous potassium hydroxide - Heat under reflux

Front (Question)

What are the reaction conditions for reacting a halogenoalkane to form a nitrile?

Back (Answer)

• Heat under reflux - Use potassium cyanide in ethanol

Front (Question)

What is a nitrile?

Back (Answer)

When there is a triple bond between the C and N

Front (Question)

What are the reaction conditions for reacting a halogenoalkane to form an amine?

Back (Answer)

-Warm with excess ethanolic ammonia

Front (Question)

What is an amine?

Back (Answer)

Organic compunds based on ammonia (NH3), but one or more of the hydrogen atoms are replaced by alkyl groups.

Front (Question)

When halogenoalkanes undergo elimination reactions, what do they form?

Back (Answer)

An alkene

Front (Question)

What are the reaction conditions for when a halogenoalkane undergoes an elimination reaction?

Back (Answer)

• React with a warm alkali dissolved in ethanol - Heat under reflux

Front (Question)

When alcohols are dehydrated, what do they form?

Back (Answer)

Alkenes

Front (Question)

What do you react alcohols with to form a chlorooalkane?

Back (Answer)

HCl or PCl5

#10

Front (Question)

How do you make an iodoalkane from an alcohol?

Back (Answer)

By reacting the alcohol with phosphorus triidide and then iodine

#11

Front (Question)

When halogenoalkanes are hydrolysed, what do they form?

Back (Answer)

Water

#12

Front (Question)

How do you compare the reactivities of halogenoalkanes?

Back (Answer)

1) Mix the halogenoalkane with water and silver nitrate solution, so that a silver halide precipitate is formed 2) Time how long it takes for the precipitate to form in each test tube

#13

Front (Question)

What happens to the rate of hydrolusis of halogneoalkens as you go down group 7?

Back (Answer)

It increases as bond enthalpy decreases

#14

Front (Question)

What hydrolyses the quickest, a primary, secondary or tertiary alcohol?

Back (Answer)

A tertiary alcohol

#15

Front (Question)

When you react alcohols with PCl5 or HCl what is produced?

Back (Answer)

A chloroalkane

#16

Front (Question)

When you react an alcohol with HBr, what is produced ?

Back (Answer)

A bromoalalkane

#17

Front (Question)

When you react an alcohol with red phosphorus and iodine, what is made?

Back (Answer)

An iodoalkane

#18

Front (Question)

When alcohols are dehydrated, what do they form?

Back (Answer)

Alkenes

#19

Front (Question)

What products are formed when an alcohol is refluxed with red phosphorus and iodine?

Back (Answer)

3RI + H3PO3

#20

Front (Question)

What do primary alcohols oxidise to?

Back (Answer)

Aldehydes and then to carboxylic acids

#21

Front (Question)

What do secondary alcohols oxidise to?

Back (Answer)

Ketones

#22

Front (Question)

What do tertiary alcohols oxidise to?

Back (Answer)

They don’t oxidise

#23

Front (Question)

What is the general formula of aldehydes and ketones?

Back (Answer)

CnH2nO

#24

Front (Question)

What is the difference between a ketone and an aldehyde?

Back (Answer)

Ketones have 2 alkyl groups attatched to the carbonyl carbon atom, whereas aldehydes only have 1
