Front (Question)

Generally referred to as derivatives of water:

Back (Answer)

alcohol ether phenol

Front (Question)

readily donates the H bonded to O in the presence of a strong base or Na and K metal making them slightly acidic.

Back (Answer)

alcohol and phenol

Front (Question)

more acidic than alcohol due to the resonance structures of phenoxide ion

Back (Answer)

phenol

Front (Question)

can be classified as primary, secondary and tertiary .

Back (Answer)

alcohol

Front (Question)

has a general formula R-O-R, is less reactive compared to alcohol and phenol

Back (Answer)

ether

Front (Question)

show the general formula of aldehyde and keton

Back (Answer)

grade yourself accordingly

Front (Question)

draw the general formula of types of alcohol

Back (Answer)

grade yourself accordingly

Front (Question)

are characterized by the presence of the carbonyl group -C=O

Back (Answer)

aldehyde and ketone

Front (Question)

Both are polar compounds which explain their relatively higher melting and boiling points compared with hydrocarbons of comparable molecular weight

Back (Answer)

aldehyde and ketone

#10

Front (Question)

Because of their polarity, these are both fairly soluble in water

Back (Answer)

aldehyde and ketone

#11

Front (Question)

test for the presence of aldehydes and ketones wherein both produce yellow crystalline derivatives

Back (Answer)

2,4-dinitrophenylhydrazine test

#12

Front (Question)

can be used to differentiate between aldehydes and ketones

Back (Answer)

oxidation reactions

#13

Front (Question)

are easily oxidized compared to ketones

Back (Answer)

aldehydes

#14

Front (Question)

resistant to oxidation

Back (Answer)

ketones

#15

Front (Question)

commonly used to determine the presence of aldehydes. The test uses silver nitrate and ammonia in water

Back (Answer)

Tollen’s test

#16

Front (Question)

containing methyl group attached to the carbonyl carbon can be determined using the iodoform test.

Back (Answer)

ketones

#17

Front (Question)

test used in experiments of carbonyl compounds

Back (Answer)

2,4-DNP Tollen’s test Iodoform Test Jones Test

#18

Front (Question)

samples to be tested

Back (Answer)

Benzaldehyde Acetone Acetaldehyde Formaldehyde 2-propanol 2-pentanone 3-pentanone Cyclohexanone (not done in the video)

#19

Front (Question)

reagents used

Back (Answer)

Tollen’s reagent 10% NaOH 2,4-dinitrophenylhydrazine 95% ethanol I2 / KI solution Chromic acid reagent

#20

Front (Question)

equipment needed

Back (Answer)

test tubes pasteur pipettes 10mL graduated cylinder

#21

Front (Question)

procedure for dinitrophenylhydrazine test

Back (Answer)

add 2 mL of ethanol to each test tube add 5 drops of acetone to first test tube add 5 drops of benzaldehyde to the second test tube add 2 mL of 2,4-dinitrophenylhydrazine shake and observe

#22

Front (Question)

• Tollen’s test procedure

Back (Answer)

Place 5 mL (3mL) Tollen’s reagent in each test tube Add 3-4 drops of formaldehyde to the first test tube, observe Add 3-4 drops of Benzaldehyde to the second test tube, observe Add 3-4 drops of acetone to third test tube, observe If there’s no reaction, place test tubes in hot water bath for two minutes

#23

Front (Question)

iodoform test procedures

Back (Answer)

Add 3 mL of 5% sodium hydroxide to each of the four test tubes Add 10 drops of acetone to the first test tubes Add 10 drops of 2-propanol to the second test tube Add 10 drops of 2-pentanone to the third test tube Add 10 drops of 3-pentanon to the third test tube Add about 10 mL of iodine solution to each test tube and shake

#24

Front (Question)

jones/chromic acid test

Back (Answer)

Place 1 mL acetaldehyde in a clean dry test tube Add 4-5 drops of chromic acid solution agitating the test tube with each addition Let stand for 10 minutes
